One day you’re driving along, and suddenly, the dreaded check engine light illuminates on your dashboard. Panic sets in, and you’re left wondering what could be wrong with your car. One of the potential reasons could be low oil levels in your engine. In this blog post, we will explore whether check engine light can come on for low oil and what to do if it does.
Understanding Check Engine Light
The check engine light is one of the most dreaded warning signs that can appear on your car’s dashboard. It’s a warning that something is wrong with your vehicle’s engine, emissions, or transmission system. The check engine light can come on for a wide range of reasons, from minor issues to severe problems that require immediate attention.
When the check engine light comes on, it’s essential to take it seriously and address the problem as soon as possible. Ignoring the light can lead to further engine damage and costly repairs down the line.
The check engine light is part of your car’s onboard diagnostic (OBD) system, which constantly monitors your vehicle’s systems for any problems. When the OBD system detects a problem, it sends a signal to the engine control module (ECM), which triggers the check engine light to turn on.
The check engine light can appear in different forms, depending on the car make and model. In some cars, the light is yellow or orange, while in others, it’s red. The light may also have a picture of an engine or simply say “check engine” or “service engine soon.”
It’s essential to understand that the check engine light does not indicate the specific problem with your car. Instead, it’s a warning sign that something is wrong and requires further investigation. To determine the specific issue, you’ll need to use an OBD scanner to read the diagnostic trouble codes (DTCs) stored in the ECM.

Low Oil and Check Engine Light
Low oil levels can cause a range of issues with your vehicle’s engine, including overheating, increased friction, and eventually engine failure. But can low oil levels cause the check engine light to come on? The answer is yes.
When your car’s oil level drops too low, it can trigger the oil pressure sensor to send a signal to the engine control module (ECM). The ECM then triggers the check engine light to turn on, indicating that something is wrong with the engine. The reason for this is that low oil levels can cause a drop in oil pressure, which can lead to engine damage.
However, it’s essential to note that low oil levels are not the only reason why the check engine light may come on. There are many other potential causes, including problems with the oxygen sensor, mass airflow sensor, fuel injector, and more.
To determine whether low oil levels are the cause of the check engine light, you’ll need to check your car’s oil level. If the oil level is low, you’ll need to add oil to your engine to bring it to the proper level. However, adding oil alone may not solve the problem, as low oil levels may indicate other underlying issues with your car’s engine.
If adding oil does not turn off the check engine light, you’ll need to take your car to a certified mechanic to diagnose and fix the problem. Ignoring the check engine light can lead to further engine damage and costly repairs, so it’s essential to address the problem as soon as possible.

Preventing Low Oil Levels and Check Engine Light
Preventing low oil levels and the resulting check engine light is crucial to maintaining the health of your car’s engine. Here are some tips to help prevent low oil levels and avoid the check engine light from turning on:
- Check your oil level regularly: It’s essential to check your car’s oil level at least once a month, or more frequently if you drive often. Refer to your car’s owner manual to find out how to check your oil level properly.
- Change your oil and oil filter regularly: Regular oil changes are vital to maintaining your car’s engine health. Consult your owner manual to determine how often you should change your oil and oil filter.
- Address any oil leaks promptly: Oil leaks can quickly lead to low oil levels and engine damage. If you notice any oil leaks, take your car to a mechanic to have them repaired promptly.
- Drive your car regularly: Letting your car sit idle for extended periods can cause oil to settle in the engine, leading to low oil levels. Regularly driving your car can help keep the oil circulating and prevent low oil levels.
- Keep an eye on your car’s performance: If you notice any unusual noises or vibrations while driving your car, have it inspected by a mechanic promptly. Catching problems early can prevent them from developing into more significant issues.
By following these tips, you can help prevent low oil levels and avoid the check engine light from turning on. Regular maintenance and addressing any issues promptly are essential to maintaining the health of your car’s engine and avoiding costly repairs down the line.
