Intermittent Fault

If the diagnostic trouble code (DTC) for this fault is stored but the adaptation values are correct, the fault is intermittent. The cause of the intermittent fault is probably a defective camshaft reset valve.

HINT: If the diagnostic trouble code (DTC) for the fault recurs after erasing diagnostic trouble codes (DTCs) and the camshaft reset valve is not defective, the variable valve timing unit may be defective.
