OBD-II Generic Error Code P0022: How to Fix It (Camshaft Position Timing Over-Retarded B2)

Q: What does error code P0022 mean?

P0022 means the camshaft position timing on bank 2 is over-retarded, meaning the camshaft is not advancing as commanded by the ECM. This is typically due to issues with the VVT system, oil flow, or timing components.

Q: Can I drive with a P0022 code?

It's not recommended to drive long distances with P0022 as it can cause poor engine performance, reduced fuel economy, and potential engine damage. Have it diagnosed and repaired as soon as possible.

Q: What are common causes of P0022?

Common causes include low or dirty engine oil, faulty VVT solenoid, clogged oil passages, stretched timing chain, or a defective camshaft position actuator (phaser).

Q: How much does it cost to fix P0022?

The cost varies widely. Simple repairs like an oil change or VVT solenoid replacement may cost $100-$400. If the timing chain or actuator needs replacement, it can be $500-$1500 or more, depending on the vehicle.

Q: Will changing the oil fix P0022?

Often yes, if the code is caused by low or dirty oil. A fresh oil change with the correct grade and proper level can restore VVT function and clear the code.

Abstract

Error code P0022 indicates that the engine control module (ECM) has detected that the camshaft timing on bank 2 is retarded (delayed) beyond the allowable limit. This can cause poor engine performance, reduced fuel economy, and rough idling. The problem is often related to the variable valve timing (VVT) system, oil flow issues, or a faulty camshaft position actuator.
