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.Google+

Check engine light has been on for 2 years. I have kept driving it and periodically it will go off. I have been told it may be something in the vacuum system or something.
