Continuing to drive the vehicle in this condition can cause severe damage to multiple internal engine components. The most common problems consist of increased engine stalling, rough engine idle, lowered fuel economy, and rattling/knocking noises from the engine.

Diagnosis: This trouble code severely impacts the drivability of your vehicle.Repair Urgency: Fix this code immediately.Issue Severity: SEVERE – Extended driving with this code can cause internal engine damage.P0022 definition: Intake Camshaft Position – Timing Over-Retarded (Bank 2).Dirty oil causes the accumulation of grime and dirt, and affects the oil control valve and the phaser.Ĭheck for any fault in the wiring and repair or replace anything that needs fixing in the camshaft OCV (oil control valve). Then, replace the engine oil and the filter, using the right oil viscosity for that particular car and engine.

How to FixĪs with many error codes, the fix for this problem will require a road test, and prior to performing the road test, you need to reset the fault code. If the solenoid still doesn’t move, then that means it’s faulty and needs replacement. If the commands of the PCM to the VVT oil flow control valve are correct, but the cam phaser is still not changing its cam timing correctly, or returning back to its base timing after delayed (retarded) command, this means the VVT valve is continuously allowing oil flow to the cam phaser, or the latter may be stuck open in a fully delayed position.Įngine off, remove the oil flow control valve and then test the solenoid through application of voltage.

For pulse width modulated control valves, the duty cycle should change with the RPM. Usually, it must be On at high engine RPM, and Off at idle.

Broken cam phaser return spring (applicable for helical gear phasers only)įor troubleshooting, use the scan tool to check the status of the VVT oil control valve.

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.
