The Check Engine light is one of the most mystifying and frustrating aspects of car ownership. It can pop on at any moment, leaving you wondering what’s wrong with your vehicle. One of the most common reasons for the Check Engine light to come on is a problem with the oil in your car. In this article, we’ll explore the relationship between the Check Engine light and oil, and what you can do to diagnose and fix the issue.
Why Does the Check Engine Light Come On for Oil?
The Check Engine light is connected to the onboard diagnostics (OBD) system in your car. This system monitors various sensors and systems in your vehicle, including the oil level and pressure. If the OBD system detects a problem with the oil, it will trigger the Check Engine light to come on. There are several reasons why the Check Engine light might come on for oil, including:
Low Oil Level
If the oil level in your car is low, the OBD system will detect this and trigger the Check Engine light. This is usually an easy fix, as you can simply add more oil to bring the level back up to the recommended level.
Oil Pressure Issues
If the oil pressure in your car is too high or too low, the OBD system will detect this and trigger the Check Engine light. This can be caused by a variety of factors, including worn engine components, clogged oil filters, or faulty oil pumps.
Oil Leaks
If there is an oil leak in your car, the OBD system will detect the loss of oil and trigger the Check Engine light. This can be caused by worn engine components, damaged oil seals, or faulty oil filters.
Oil Quality Issues
If the oil in your car is old or degraded, the OBD system may detect this and trigger the Check Engine light. This can be caused by using the wrong type of oil for your car, or by neglecting to change the oil regularly.
In this article, we’ll explore these and other reasons why the Check Engine light might come on for oil, and provide tips and advice on how to diagnose and fix the issue. Whether you’re a seasoned mechanic or a DIY novice, this article will provide you with the information you need to keep your car running smoothly and avoid costly repairs.

Can Oil Cause the Check Engine Light to Come On?
Yes, low oil levels or dirty oil can cause the Check Engine light to come on. Here are some reasons why:
Low Oil Levels: If your oil levels are low, the Check Engine light may come on to alert you to the problem. This is because the ECM is designed to monitor the oil level and alert you if it falls below a certain threshold. Low oil levels can cause engine damage, so it’s essential to check your oil levels regularly and top them off as needed.
Dirty Oil: Dirty oil can also cause the Check Engine light to come on. When oil becomes dirty, it can’t lubricate your engine properly, which can lead to increased engine wear and tear. If your oil is dirty, it’s essential to change it as soon as possible to prevent further damage to your engine.
How to Check Your Oil Levels
Checking your oil levels is a simple process that you can do yourself. Here’s how:
Step 1: Make sure your car is parked on a level surface and turned off.
Step 2: Open the hood of your car and locate the oil dipstick. It’s usually labeled “Oil” or have an oil can symbol on it.
Step 3: Pull out the dipstick and wipe it clean with a rag or paper towel.
Step 4: Insert the dipstick back into the oil reservoir and pull it out again. The dipstick will now be coated with oil.
Step 5: Check the oil level by looking at the end of the dipstick. The oil level should be between the “MIN” and “MAX” marks on the dipstick. (See Also: Can You Add Oil While Engine Is Running)

Will Check Engine Come On For Oil FAQs
Why does my check engine light come on when I’m running low on oil?
The check engine light is designed to alert you to potential issues with your vehicle’s performance. When your oil level is low, it can cause the engine to overheat, leading to a warning light on the dashboard. This is because oil helps to lubricate the engine and keep it running smoothly. Without enough oil, the engine can become damaged, which is why the check engine light is triggered.
Can a faulty oil sensor cause the check engine light to come on?
Yes, a faulty oil sensor can cause the check engine light to come on. The oil sensor is responsible for monitoring the oil level and sending a signal to the engine computer if it’s low. If the sensor is faulty, it may send a false signal, triggering the check engine light even if the oil level is fine. In this case, it’s essential to have the sensor checked and replaced if necessary.
Will the check engine light come on if I’m using the wrong type of oil?
Yes, using the wrong type of oil can cause the check engine light to come on. If you’re using the wrong viscosity or type of oil for your vehicle, it can affect the engine’s performance and lead to a warning light. Make sure to check your owner’s manual to find out what type of oil is recommended for your vehicle.
Can a clogged oil filter cause the check engine light to come on?
Yes, a clogged oil filter can cause the check engine light to come on. A clogged filter can restrict oil flow to the engine, leading to decreased performance and triggering the check engine light. It’s essential to replace the oil filter regularly to ensure proper oil flow and prevent damage to the engine.
What should I do if the check engine light comes on when I’m running low on oil?
If the check engine light comes on when you’re running low on oil, it’s essential to stop driving and add oil to your vehicle as soon as possible. Continuing to drive with low oil levels can cause serious damage to the engine, leading to costly repairs. Once you’ve added oil, restart the engine and check the dashboard to ensure the light has gone off. If the light remains on, it may be a sign of a more serious issue and you should have your vehicle checked by a mechanic.
