A check engine light can indicate many issues such as sensor failures, misfires, emissions problems, fuel system issues, or engine performance concerns. A professional scan is the best way to identify the exact cause.

It depends. If the light is steady, the vehicle may still be drivable, but the issue should be diagnosed soon. If the light is flashing, it usually indicates a serious problem and driving may cause engine damage.

Resetting the light without diagnosing the issue is not recommended. The light will usually return if the underlying problem is still present, and ignoring it may lead to more expensive repairs.

Common causes include oxygen sensor failure, loose gas cap, faulty spark plugs, ignition coil issues, catalytic converter problems, vacuum leaks, and fuel system faults.

A basic scan can take 15–30 minutes. A full diagnosis may take longer depending on the complexity of the problem and testing required.
