Check Engine Light When Car Is Off
What Does It Mean?
When the check engine light comes on, it means that the engine control module (ECM) has detected a problem with the car’s engine. The ECM is a computer that monitors the engine’s performance and emissions. When it detects a problem, it will turn on the check engine light to alert the driver.
There are many possible reasons why the check engine light might come on. Some of the most common reasons include:
- Loose or damaged gas cap
- Faulty oxygen sensor
- Spark plug problems
- Ignition coil problems
- Exhaust system problems
- Emission control system problems
What Should I Do?
If the check engine light comes on, you should take your car to a mechanic as soon as possible. The mechanic will be able to diagnose the problem and make the necessary repairs.
In some cases, you may be able to fix the problem yourself. For example, if the check engine light comes on because of a loose gas cap, you can simply tighten the cap and the light will go off.
However, if the check engine light comes on for any other reason, you should take your car to a mechanic. Trying to fix the problem yourself could make the problem worse.
Can I Drive My Car With the Check Engine Light On?
In most cases, you can still drive your car with the check engine light on. However, it is important to have the problem diagnosed and repaired as soon as possible. Driving with the check engine light on can damage your car’s engine and other components.
If the check engine light is flashing, it means that there is a serious problem with your car’s engine. You should stop driving immediately and have your car towed to a mechanic.
Conclusion
The check engine light is a warning system that tells you that there is a problem with your car’s engine. If the check engine light comes on, you should take your car to a mechanic as soon as possible to have the problem diagnosed and repaired.
