Report A Problem

The Check Engine Light may illuminate because the mass air flow sensor sends incorrect information to the engine control computer. This can cause a loss of power on acceleration. A failed mass air flow sensor will require replacement.

Occasionally, the Check Engine Light is illuminated due to failures in the evaporative emission (EVAP) system. Our technicians tell us that proper diagnoses is generally required to confirm the exact fault causing the warning light to come on.
