Check Engine Light FAQ
Is it safe to drive with the light on?
A steady light usually means a non-critical emissions issue, but a flashing light indicates a severe misfire that can damage your catalytic converter. Flashing lights require immediate service.
Will this affect my smog test?
Yes. In California, an active check engine light is an automatic failure. Even if you clear the code, the vehicle will not pass until the internal monitors are "Ready."
Can a loose gas cap cause the light?
Yes, a loose or damaged gas cap can trigger an EVAP system code. We check the simplest possibilities first during our inspection.
