What Does P0022 Mean?
The PCM has detected that the Bank 2 intake camshaft timing is more retarded than the commanded target. This is the Bank 2 equivalent of P0012. The VVT actuator on Bank 2 is not advancing the intake cam when commanded, causing performance loss particularly during acceleration.
Common Causes
30%
Low engine oil or degraded oil unable to adequately pressurize the VVT phaser
30%
Bank 2 intake VVT solenoid stuck in the retarded position
20%
Clogged filter screen on the Bank 2 VVT solenoid restricting oil flow
15%
Bank 2 intake VVT phaser locking pin stuck in default retarded position
5%
Timing chain stretch on Bank 2 preventing proper cam advance
Diagnostic Steps
1
Check engine oil level and condition; verify correct viscosity and change if overdue or degraded
2
Monitor Bank 2 intake cam advance via live data — if stuck near 0 degrees when commanding 15-25 degrees, the system cannot advance
3
Test the Bank 2 intake VVT solenoid: measure resistance (6.9-7.9 ohms), command duty cycle sweep, and verify mechanical actuation
4
Pull the Bank 2 intake VVT solenoid and inspect its mesh filter screen — a common failure point for sludge accumulation
5
Verify adequate oil pressure at the Bank 2 VVT feed by checking main oil gallery pressure (minimum 25 PSI at 2000 RPM)
Estimated Repair Cost
$50 - $800
Parts + labor, varies by vehicle and location
The PCM has detected that the Bank 2 intake camshaft timing is more retarded than the commanded target. This is the Bank 2 equivalent of P0012. The VVT actuator on Bank 2 is not advancing the intake cam when commanded, causing performance loss particularly during acceleration.
The most common cause of P0022 (Intake Camshaft Position Timing - Over-Retarded (Bank 2)) is: Low engine oil or degraded oil unable to adequately pressurize the VVT phaser
Typical repair costs for P0022 range from $50 to $800, depending on the vehicle, location, and whether you do it yourself or go to a shop.
Reduced acceleration performance and increased fuel consumption. The vehicle is safe to drive but should be repaired before extended highway driving to maintain proper emissions compliance.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to P0022 to identify the root cause.
