The Check Engine Light may illuminate due to a defective charcoal canister vent control valve. The charcoal canister is a component in the Evaporative emissions (EVAP) system. Our technicians tell us a failed vent valve will require replacement.

The Check Engine Light may illuminate because the sensor that monitors the engine's intake valve timing stops working (Intake Valve Timing Control Position Sensor). Replacement of the failed sensor will commonly correct this problem.
