Warning light guide
Learn what a check engine light can mean, when to stop driving, and how professional diagnostics protect your repair budget.
A check engine light can be triggered by emissions, ignition, fuel, air, sensor, electrical, or mechanical issues. The code is a starting point, not a final diagnosis.
A flashing check engine light is more urgent and can indicate a misfire severe enough to damage the catalytic converter.
Reduce unnecessary driving if the vehicle runs poorly, and schedule diagnostics if the light stays on.
