What a check engine light can mean
The light can come on for something as simple as a loose gas cap or as serious as a misfire that can damage your catalytic converter. Common causes include:
- Oxygen sensor or mass airflow sensor faults
- Ignition coils and spark plugs causing misfires
- Evaporative (EVAP) system leaks
- Catalytic converter efficiency
- Vacuum leaks and fuel system problems
Steady light vs. flashing light
A steady light means get it checked soon. A flashing light usually means an active misfire. Reduce speed, avoid hard acceleration and get the car in as soon as you can to avoid costly damage.
