Low oil pressure light coming on (4 common causes)

How To Diagnose & Fix The Oil Pressure Low Stop Engine Problem?

Now let’s see how you can diagnose and fix the oil pressure low stop engine message that popped on your cluster. What you can do about this?

Well, the first thing that you can do is to stop the car or drive to the nearest gas station and check the oil level. This is essential. The probability of running low on oil is there and if you are you need to top off the oil on your car and this hopefully will fix the issue.

Also, flush the oil on your car and see if you get the same problem with fresh oil and filter. If you do, then the problem lies somewhere in the oil pump, oil pressure sensor, or possibly low compression.

The first thing that you need to check is the oil pressure switch and test the car with an OBD2 scanner. Check if you get a P0521 or a similar code from the ones that we listed in the previous chapters. These indicate problems with the oil pressure switch. If the switch is broken then you need to replace it.

How Do You Diagnose Low Oil Pressure?

• Check the Oil Level: The first step is to check if there’s enough oil in the engine. This can be done using the dipstick.
• Check the Oil Pressure Sensor: The sensor could be faulty and give an inaccurate reading. You can use an oil pressure gauge to verify.
• Inspect the Oil Filter: A clogged oil filter can cause low oil pressure. If the filter is dirty, consider replacing it.
• Examine the Oil Pump: A failing oil pump can lead to low oil pressure. Listen for any unusual noises that might indicate a problem.
• Assess the Engine Oil Viscosity: Use the correct oil viscosity as recommended by your vehicle’s manufacturer. Too thick or too thin oil can cause low oil pressure.
• Look for Oil Leaks: Check for any visible signs of oil leaks in your engine.
• Check the Oil Pressure Relief Valve: If the valve is stuck open, this can cause low oil pressure. It may need cleaning or replacing.
• Inspect Internal Engine Components: Worn-out bearings or other internal engine parts can cause low oil pressure. This usually needs professional assessment.

Your Next Steps

If you experience these problems with your Ford Edge low engine oil pressure, then you need to first check your oil level. It is the initial step to take when it comes to diagnosing the low pressure to the oil.  When you have a drastically low oil level, then you should top up. 

But then again, there may be some reasons why this happens. It could be a leak or some other issue. This is why you need to inspect for any leaks that may be causing the engine oil level to drop quickly. 

Also, you should check the sensor that is used for reading the oil level. If your vehicle’s sensor is faulty, then the reading automatically becomes a false low pressure, which is then sent to the ECM. So, be sure to inspect the sensor and maybe change it when there is an issue. 

And of course, nothing beats taking your vehicle to the mechanic for further inspections. When you allow the oil pressure to stay low and keep driving your car, this can jeopardize not just your engine but also your life!

A low oil pressure issue requires prompt and thorough attention. When you have a problem such as this one, it is best to get it resolved sooner than later. Otherwise, your engine runs the risk of severe damage, which can accumulate further issues and more expensive repairs. 

While your car’s vital fluids are essential, there are those that need a special kind of maintenance such as the engine oil. This is your vehicle’s lifeblood, and you need to make it a priority to address any issue with it to stay safe on the road. Pay close attention to warning lights as well as the message your sensor sends out to determine what is going on with your vehicle and take the right action sooner than later.

Faulty Engine Oil Pump

At the heart of the lubrication system is the oil pump.

This one component is responsible for delivering the engine’s oil pressure.

From a design standpoint, oil pumps should last the entire engine life of the engine. However, they can fail before that depending on vehicle maintenance and usage.

If the oil changes intervals were too prolonged, the oil level was kept too low for extended periods of time, or the vehicle was used in demanding assignments such as towing, police work, ambulance, and similar jobs, then the oil pump may fail prematurely.

Some symptoms that may indicate a faulty oil pump are the following:

1. Low oil pressure.
2. Higher than normal engine temperature.
3. Clinking noise.
4. Oil leak coming from the oil pump.

In Conclusion

Low engine oil pressure is a serious issue that can lead to significant damage to your vehicle’s engine.

The causes can range from low oil levels, faulty oil pressure sensors, incorrect oil viscosity, clogged oil filters, and defective oil pumps to worn-out internal engine components.

Symptoms of low oil pressure are often noticeable and include an illuminated oil pressure warning light, unusual engine noises, decreased engine performance, and the smell of burning oil. It’s crucial to address these symptoms immediately to prevent further damage.

Regular maintenance, using the correct grade of oil, and paying attention to your car’s warning signs can help prevent low oil pressure scenarios.

Is It OK To Drive With Low Oil Pressure?

No, it is not safe to drive with low oil pressure. The oil in your vehicle serves a critical function – it lubricates the engine’s internal components, reduces friction, and helps to cool the engine.

Low oil pressure means that there isn’t enough oil flowing inside the engine to perform these tasks properly, which can lead to increased wear and tear on the engine parts and potential overheating.

Driving with low oil pressure can cause serious, sometimes irreparable damage to your vehicle’s engine.

If the oil pressure is too low, the engine may not get the lubrication it needs, leading to increased friction between its moving parts.

This can eventually cause the engine to seize up, which can be a very costly problem to fix.

Wrong oil viscosity

Using oil viscosity other than recommended by the manufacturer for your Nissan Qashqai can also turn on the low oil pressure light . It can cause a variety of issues in your vehicle, as the engine oil plays a crucial role in lubricating, cooling, and cleaning the engine components. The viscosity of the oil refers to its thickness or resistance to flow, and different engines require different oil viscosities to function properly.

Oil is too thick, or too thin

Using oil with a viscosity that is too thick can cause issues with oil flow and lubrication, leading to increased engine wear and decreased fuel efficiency. On the other hand, using oil with a viscosity that is too thin can lead to decreased engine protection, decreased fuel efficiency, and increased oil consumption.

Verify the oil viscosity for your engine

To prevent issues with the wrong oil viscosity, it is important to refer to the owner’s manual or consult with a qualified mechanic to determine the correct oil viscosity for your vehicle. When changing the oil, be sure to use oil with the correct viscosity rating and type recommended by the manufacturer.

If you suspect that the wrong oil viscosity has been used in your vehicle, it is important to have it inspected by a qualified mechanic.

Low Oil Pressure Causes: Toyota Corolla

There are many things that can cause low oil pressure.  Below, we’ll review the most common causes:

No Oil

The number one reason that your Corolla would have low oil pressure would be a lack of oil.  The first thing you should do, is check your engine oil level.

If the engine oil level appears to be low (or empty), you’ll need to fill it up. Do not drive a vehicle with low engine oil to the store to buy more oil. Running without enough oil to keep pressure in the crank case will certainly look up the engine.  It’s not a matter of if it will lock up the engine, it’s only a matter of when.

Bad Oil Pump

The oil pump is responsible for taking the oil from the oil pan and pumping it through your Corolla’s engine.  When it begins wearing out, its ability to pump oil will be diminished.

There is a screen in most oil pumps that keeps large debris from entering.  Eventually though, enough debris can enter the pump to do some lasting damage to the pump capacity.

Air in Oil

If the oil level is significantly lower in the pan than it should be, air can get into the oil pump and aerate the oil.  Think about it like the foam on a cappuccino or beer.  It’s the same liquid, but has totally different characteristics when foamy.

This same problem can occur when there is too much oil as well.  Check the oil level and make sure it’s ok, and that it looks ok.

Dirty Engine/Dirty Oil

Engines that run long enough without any sort of regular oil change schedule can get so dirty on the inside that it begins to build up inside the crank case. Or, the oil itself could just be so dirty that it no longer cycles through the engine properly, which causes low oil pressure.

If you have no idea when the last time your Corolla’s oil was changed, or if you happen to have done a lot of towing, or if your oil change is overdue, changing the oil itself may vary well solve the problem.

Pickup Tube

There is a tube in your Corolla that takes the oil from the pan to the oil pump.  This is called the pickup tube.  This tube can fall out, which will cause no oil to get to the oil pump.

Clogged Oil Filter

Modern engines use a bypass valves to keep oil flowing to the engine even when the filter is clogged.  This bypass valve is activated when there is too much resistance from the oil filter. This valve can only allow so much oil through, and may trigger the oil light.

Low Oil Pressure Diagnosis: Toyota Corolla

Here are a few of the steps that you can pursue to diagnose your low oil pressure condition:

Check the Oil Level

As stated above, checking the oil level in your Corolla is definitely the place to start diagnosing low oil pressure.  If the oil level is really low, you’ll need to fill it up until it’s back to the full mark.  This may solve the problem.

Keep in mind that if the oil has leaked out once, it will leak out again.  You’ll need to start checking it much more often.

Check to See if the Oil Pressure Sending Unit is working

Modern vehicles use an electric oil pressure sending unit.  If your Corolla’s sensor has gone bad, it’ll shoot a false low pressure reading to the ECM.  One of the first things that people do when they have the low oil pressure light is to change out this sensor to see if that rectifies the problem.

Here’s a good article on how to check the oil pressure sensor from itstillruns.

Frequently Asked Questions

Can I continue driving my Qashqai with low oil pressure light on?

If the low oil pressure warning light turns on in your Nissan Qashqai while you are driving, it is important to take immediate action to avoid potential engine damage. The first step is to safely stop the vehicle as soon as possible, while being mindful of traffic and other road hazards. Once you have come to a safe stop, you should turn off the engine.

It is important to note that driving with low oil pressure can cause serious damage to your engine, as the oil serves as a lubricant to prevent friction and wear between moving parts. If the engine is run without enough oil pressure, it can lead to increased heat and friction, which can cause damage or even complete engine failure.

How long can an engine run with low oil pressure?

It’s difficult to say exactly how long an engine can run with low oil pressure, as it depends on several factors such as the severity of the issue and how quickly the problem is addressed. In general, it’s not recommended to run an engine with low oil pressure for any longer than necessary, as it can lead to significant engine damage or even complete engine failure.

Can I just add oil to my car?

If your vehicle’s low oil pressure warning light has turned on, adding oil to the engine may help increase the oil pressure and prevent further damage, but only if the cause is due to low oil level.

Before adding oil, make sure to check the owner’s manual to determine the correct type and amount of oil needed for your vehicle. It’s also important to check the oil level and ensure that it is not above the maximum level.

Adding too much oil can cause foaming and reduce the oil’s ability to lubricate the engine properly, which can cause further damage. It’s best to add oil in small increments, checking the oil level frequently to ensure that the oil level is within the recommended range.

Will a bad oil pump throw a code?

A bad oil pump can cause low oil pressure and trigger the low oil pressure warning light, but it may not always throw a diagnostic trouble code (DTC) on the OBD system.

The reason for this is that the oil pressure sensor detects the low oil pressure and sends a signal to the engine control module (ECM) which then illuminates the low oil pressure warning light. However, if the oil pressure sensor is working properly, the ECM may not register a fault code related to the oil pump.

That being said, if the oil pump is failing and causing low oil pressure, it may trigger other DTCs related to engine performance or oil pressure. For example, if the oil pressure is low and causing engine misfires, it may trigger a DTC related to misfires. Similarly, if the low oil pressure is causing other engine components to fail, such as the variable valve timing system, it may trigger a DTC related to that system.

Can low oil pressure cause an engine to misfire?

Yes, low oil pressure can cause misfires in an engine. Misfires occur when one or more cylinders in the engine fail to ignite properly, which can cause a variety of symptoms such as a rough idle, decreased power, and increased emissions.

Low oil pressure can cause misfires in several ways. First, low oil pressure can lead to insufficient lubrication of critical engine components, such as the valve train and bearings. Without proper lubrication, these components can wear and fail, leading to engine misfires.

Secondly, low oil pressure can cause variable valve timing (VVT) systems to malfunction, which can also cause misfires. Many modern engines use VVT systems to optimize engine performance and fuel efficiency. These systems rely on oil pressure to operate properly, and if oil pressure is too low, they may not function as intended.

Will the check engine light come on if oil pressure is low?

In some cases, a low oil pressure condition may trigger the check engine light to come on. The check engine light is designed to come on when the engine control module (ECM) detects a fault with one of the vehicle’s systems or components. If low oil pressure is detected as a fault, the ECM may illuminate the check engine light and store a code in its memory for retrieval with a diagnostic scanner.

Defective Engine Oil Pressure Sensor

Last but not least, the entire situation of low oil pressure could be a false positive.

It’s often a good idea before taking on major repairs to check the engine’s oil pressure sensor first.

Depending on the year and maker of your car this sensor could as simple as an electrical switch that sends to the Electronic Control Unit (ECU) a signal indicating low oil pressure or could be a more fully-featured pressure sensor. 

The best strategy to discard a possible sensor problem is to use an automotive (OBD) scanner to perform a quick check.

Here are the steps to check for a faulty or failing oil pressure sensor using an OBD scanner:

1. Connect the scanner to the vehicle diagnostic port and turn the ignition switch on (engine off).
2. Look in the data stream for the oil pressure sensor value.
3. For switch-based sensors, you can unplug its connector and check the scanner screen. Take note of the reading. With the sensor still unplugged use a wire to bypass the signal to the ECU. Again take note of the sensor value. Sensor signal should change from ON to OFF (or vice-versa) when you bypass the signal. This is the normal behavior indicating a working sensor.
4. Fully-featured pressure sensor diagnostic is very similar. An unplugged sensor should indicate no pressure on the screen and a bypassed sensor should go to full pressure. If the vehicle is equipped with an oil pressure gauge then you should be able to see the changes in the instrument panel.

Facts: What Does Oil Pressure Low Stop Engine Message Mean?

1. An Oil Pressure Low Stop Engine message means that your car’s engine has detected a lower level of oil than what should be present in the engine.

10. Consulting with a mechanic can help you make an official diagnosis and determine the best way to resolve the Oil Pressure Low Stop Engine light.

How To Fix Low Oil Pressure In a Car

• Check Oil Levels: The first step is to check your oil levels using the dipstick. If the oil level is lower than it should be, add more oil until it reaches the recommended level.
• Check Oil Quality: Look at the color and consistency of the oil on the dipstick. If it’s dark and dirty, it may be time for an oil change.
• Change Oil Filter: A clogged oil filter can cause low oil pressure. Replace the filter and see if that solves the problem.
• Inspect Oil Pump: The oil pump circulates oil throughout the engine. If it’s damaged or not working properly, it could be causing low oil pressure. You may need a mechanic to inspect and potentially replace the pump.
• Look for Oil Leaks: If your car is leaking oil, it could lead to low oil pressure. Check under the car for any signs of oil leaks and have them repaired.
• Check Engine for Damage: If all else fails, there could be damage within the engine causing the low oil pressure. This would require a professional mechanic to diagnose and repair.

Types Of Oil Pressure

Now let’s quickly cover the types of oil pressure that are out there before we dive into the oil pressure low stop engine problem. Knowing the types will help you determine what is the right normal pressure on your car. So, let’s get into it.

2. Normal Oil Pressure

The second type of oil pressure that we are going to cover before we learn more about the oil pressure low stop engine problem is the normal oil pressure.

The normal oil pressure is somewhere between 25 and 65 PSI. This is the sweet spot when it comes to oil pressure and you should always focus that your oil pressure is in this range. Now let’s move on to the last type.

3. Low Oil Pressure

The last type of oil pressure that we are going to cover before we learn more about the oil pressure low stop engine problem is the low oil pressure.

Whenever you are getting a situation of low oil pressure warning that tells you that you need to stop your engine because of low oil pressure. The only way around this would be to deeply inspect the engine and move on from there.

Low oil pressure is considered to be anything below 25 PSI. So, if the pressure meter is below this range, then you have a problem with the oil pressure low stop engine. Now let’s move on to the next topic and discuss more on the low oil pressure light

Low Oil Pressure Light

Now let’s discuss the low oil pressure light. What this light means in the first place. Does it indicate oil pressure low stop engine situation or something else?

Well, sort of. When the oil light is on, you might be having a car that is low on oil. You might be having a leak from somewhere that is causing this light to turn on. Or if you overfilled the oil, the light might turn on because of too much oil.

This light is controlled by the engine oil pressure sensor known also as an oil pressure switch. This light doesn’t necessarily tell you that you are having an issue with low oil pressure keep that in mind. For the right data, you should always monitor the oil pressure gauge and the needle of this gauge and make sure that every time it is at the right spot. Now let’s cover some of the most common situations that indicate oil pressure low stop engine.

FAQs

Oil not changed on time

Oil that has not been changed on time or is too old can also contribute to low oil pressure in your Qashqai. Over time, engine oil breaks down and becomes less effective at lubricating the engine and removing contaminants. As a result, the oil pressure can drop and cause the low oil pressure warning light to turn on.

May need to flush the engine

If the oil in your Qashqai is too old or has not been changed on time, it’s important to have it changed as soon as possible. An oil change will replace the old oil with fresh oil and help restore proper oil pressure. In some cases, it may also be necessary to flush the engine to remove any built-up contaminants that can contribute to low oil pressure.

Always change engine oil on time

Regular oil changes can help prevent low oil pressure issues in your Qashqai and prolong the life of the engine. It’s important to consult the owner’s manual for specific oil change intervals and follow the manufacturer’s recommendations to ensure proper engine lubrication and prevent costly repairs.

Oil pressure sensor malfunction

A bad oil pressure sensor can cause the low oil pressure warning light to turn on in your Qashqai. The oil pressure sensor is responsible for monitoring the oil pressure and sending a signal to the vehicle’s computer, which in turn illuminates the warning light on the dashboard if the oil pressure drops below a certain level.

If the oil pressure sensor is malfunctioning, it may send a false signal to the vehicle’s computer, causing the low oil pressure warning light to turn on even if the oil pressure is actually within a safe range. Alternatively, a faulty sensor may not send a signal at all, causing the warning light to remain off even if the oil pressure is dangerously low.

How to check a faulty oil pressure sensor

If the oil pressure sensor is malfunctioning, it may trigger an OBD fault code in your vehicle’s engine control module (ECM). This fault code can be read using a diagnostic scanner or code reader, and will provide information about the specific nature of the issue with the oil pressure sensor.

Some common fault codes that may be associated with a faulty oil pressure sensor include:

• P0520: Engine Oil Pressure Sensor/Switch Circuit Malfunction
• P0521: Engine Oil Pressure Sensor/Switch Circuit Range/Performance

Регулярное техническое обслуживание и внимание к состоянию двигателя — важные аспекты поддержания его нормальной работы

Causes of Ford Edge Low Engine Oil Pressure

Let us look into these typical causes of a low engine oil pressure with your Ford Edge. Here they are:

1. Lack of oil

The most common cause of a low engine oil pressure is the lack of oil. What this means is that your engine oil has gone lower than it should, or it may already be empty. Hence, you should make it a point to fill it right up. Avoid driving your vehicle when the engine oil is low. It should be your top priority to get more oil to top up since the crankcase will be in peril, causing your engine to lock up.

2. Faulty oil pump

Next up, we have an oil pump issue. This component takes your oil from your oil pan and then pumps it to the engine. When your oil pump is already malfunctioning, it no longer becomes capable of pumpkin oil. There is also a screen or a filter in your oil pump, and this prevents debris from getting inside. But when there is a lot of debris in the long run, this will cause a deterioration to your pump’s capacity.

3. Air in your oil

Another common reason for a Ford Edge low engine oil pressure issue is having air in your oil. When you have a very low oil level in your pan, then air can enter into the pump and cause the oil to aerate. It is much like froth to your beer or cappuccino – when you have more air in the oil, it becomes foamy or frothy. As a result, be sure to prevent having air getting into the oil pump to prevent this aeration concern.

4. Dirt in oil

You want to make sure that your engine oil is clean and dirt-free. This is why regular oil change is essential as this prevents any debris or gunk on the interior that will then accumulate in your crankcase. Moreover, the oil may simply become dirty, which is why it is unable to cycle through your engine correctly. Hence, low oil pressure occurs.

So, if you are uncertain when you had your oil changed, or you have performed so much towing of heavy loads, then you should make it a point to get an oil change. Otherwise, the engine oil pressure is likely to become too low.

5. Pickup tube issue

Your Ford Edge has a tube, which is responsible for taking oil from your pan and into the oil pump. When the tube falls out eventually, it no longer makes it possible for the oil to enter your oil pump.

Hence, be sure to inspect the tube and that it is still working as it should.

6. Oil filter clog

Many engines have a bypass valve that allows oil to keep flowing to your engine. This is a concern that can also impact the integrity of your Ford Edge’s engine oil pressure. When there is so much resistance from your oil filter, this activates the bypass valve. Since it can only handle so much engine oil, the oil light becomes triggered when there is more than it can handle.

Common Situations With Low Oil Pressure

As we mentioned above, in the following chapters, we are going to list the two most common situations that tell give you a warning of oil pressure low stop engine. And you need to be prepared for both of them or you possibly have already come across one of these. So, what are these situations? Let’s elaborate.

Oil Pressure Low Stop Engine But Oil Is Full

The first situation that we are going to cover is with the oil pressure low stop engine but oil is full. This is a situation that can be somewhat misleading. Why you would get this type of message?

Well, there could be a couple of things. Either the oil has become sludgy and not changed for a long time, your oil filter is clogged, or eventually, your oil pressure switch is bad and is basically misguiding you into thinking that you have a problem with the oil pressure of your car. So, beware of these situations. Now let’s move on to the next.

Oil Pressure Low Stop Engine Comes On And Off

The second situation is when the oil pressure low stop engine comes on and off. So, why is this the case?

Well, there could be a few causes for this situation. More precisely a problem with sludge inside of the engine. If the passageways are not cleared, or possibly the oil pump is not performing as it should cause problems like this to happen.

The important thing for you is not to panic and try to diagnose the problem. Later on, we are going to explain how it is done. The next thing we would like to talk about is the symptoms of an oil pressure low stop engine. What symptoms you could expect when the oil pressure is low, let’s elaborate.

Dirty or Degraded Engine Oil

Engine oil is subject to several conditions that degrade its properties over time. Some of these conditions are:

• The constant cycle of heating and cooling down.
• The friction forces of mechanical parts.
• The dirt, engine metal debris, and fuel contaminants that combine with oil.

The contamination/degradation process is inevitable due to the oil working environment. That’s why paying attention to the suggested oil change interval is important.

Typically, fully synthetic oil service intervals range between 7,500 to 10,000 miles depending on vehicle usage, brand, and engine design. The more you wait between changes the more likely your engine will suffer the consequences of degraded engine oil:

• Diminished cleaning power.
• Reduced wear protection.
• Higher viscosity

Arguably, the most dangerous consequence of all is the last one, higher viscosity which is discussed in detail in the next section.

Use an OBD Scanner for diagnosis

Using an OBD (On-Board Diagnostics) scanner is a great way to diagnose low oil pressure issues in your Nissan Qashqai. An OBD scanner can connect to your vehicle’s OBD-II port and retrieve diagnostic trouble codes (DTCs) that can help pinpoint the cause of the low oil pressure warning light.

When the low oil pressure warning light turns on, the OBD scanner can be used to retrieve the specific DTC associated with the issue.

Once the DTC has been retrieved, the OBD scanner can also be used to monitor live engine data such as oil pressure, engine RPM, and engine temperature. This data can help identify issues such as a failed oil pressure sensor or a clogged oil pickup screen.

While an OBD scanner can be a useful tool for diagnosing low oil pressure issues in your Qashqai, it’s important to note that it may not be able to diagnose all possible causes of low oil pressure. In some cases, a visual inspection of the engine or additional diagnostic tests may be necessary to identify the root cause of the issue.

If you’re not comfortable using an OBD scanner or don’t have access to one, it’s important to have your Qashqai inspected by a qualified mechanic who can diagnose and repair low oil pressure issues to prevent further damage to the engine.
