Check Engine Light Doesn’t Come On When Starting Car
Why is the Check Engine Light Not Coming On?
The check engine light (CEL) is designed to illuminate when there is a problem with your car’s engine or emissions system. It is a warning light that should not be ignored, as it could indicate a serious issue that needs to be addressed.
There are several reasons why the CEL may not be coming on when you start your car:
- The CEL bulb may be burned out.
- The wiring to the CEL may be damaged.
- The CEL sensor may be faulty.
- The engine control module (ECM) may not be sending a signal to the CEL to turn on.
How to Fix the Check Engine Light
If you suspect that the CEL is not working properly, you should take your car to a mechanic to have it diagnosed. The mechanic will be able to determine the cause of the problem and make the necessary repairs.
In some cases, you may be able to fix the problem yourself. If the CEL bulb is burned out, you can simply replace it. If the wiring to the CEL is damaged, you can repair or replace the wiring.
However, if the CEL sensor or the ECM is faulty, you will need to take your car to a mechanic for repairs.
What to Do If the Check Engine Light Doesn’t Come On
If the CEL does not come on when you start your car, it is important to be aware of any other symptoms that your car may be experiencing. These symptoms could include:
- Engine performance problems
- Increased fuel consumption
- Emissions problems
If you notice any of these symptoms, you should take your car to a mechanic to have it diagnosed. Even if the CEL is not coming on, there could still be a problem with your car that needs to be addressed.
Conclusion
The check engine light is an important warning light that should not be ignored. If the CEL is not coming on when you start your car, it is important to have it diagnosed by a mechanic. The mechanic will be able to determine the cause of the problem and make the necessary repairs.
