Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Check Engine Light
This CHECK ENGINE light is located on the instrument panel and has 2 functions. It informs the driver of system faults and allows the technician a way to access ECM fault codes.
As a system check, light should come on when ignition switch is in the ON position and engine is not running. When engine is running, light will go out unless a fault is present. If an indicated fault goes away, light will go out in 10 seconds, but fault code will remain stored in ECM.
