Can a Dying Car Battery Cause Check Engine Light?
A dying car battery can cause a check engine light to come on. This is because the battery is responsible for providing power to the car’s electrical system, including the engine control module (ECM). When the battery is not able to provide enough power, the ECM may not be able to function properly, which can cause the check engine light to come on.
In addition to causing the check engine light to come on, a dying car battery can also cause other problems, such as:
- Difficulty starting the car
- Dimming headlights
- Loss of power accessories, such as the radio and air conditioning
If you are experiencing any of these symptoms, it is important to have your battery checked as soon as possible. A dying battery can be dangerous, and it can cause serious damage to your car if it is not replaced.
