![]() ![]() Sticking of VVT oil flow control valve due to varnish buildup or oil contamination.Continuous oil flow to the VCT position chamber.Wiring problems (caused by harness or wiring) in intake timing control valve solenoid system, causing the VVT oil flow control valve to continuously receive voltage.Possible CausesĮrror Code P0022 is usually caused by incorrect camshaft timing or a defective (stuck open) VVT oil flow control valve. Emission of excessive fumes out of the engineĭrive complains may vary, depending on the camshaft timing.Emission of black smoke out of the tailpipe.Decrease in fuel mileage/ poor fuel efficiency.Apart from that, the common symptoms include: Obviously, this error code activates the Check Engine light of the vehicle. The “A” camshaft refers to either the intake, front, or left camshaft. ![]() This condition could result during the advancing or retarding phase of the camshaft timing. DefinitionĮrror Code P0022 is a generic OBD-II error code, which, as mentioned above, entails a problem in the Bank 2’s intake camshaft timing, and that it’s more retarded (delayed) that what the PCM commands it to be. This indicates a problem on the VVT or VCT (variable valve timing, variable camshaft timing, respectively) components of the vehicle’s PCM (powertrain control module, also known as ECM), which means there’s an over-retarded (over delayed) timing condition on the intake camshaft timing of bank 2. Error Code P0022 is defined as Camshaft Position A – Timing Over-Retarded, Bank 2. ![]()
