The intake camshaft on bank 1 is more retarded than commanded by the ECM. This reduces engine performance and efficiency. Often related to oil viscosity issues or a failing VVT actuator.
Same as P0011 but on bank 2 (the opposite cylinder bank on V-engines). The intake cam is too far advanced due to oil or VVT solenoid issues.
The ECM detected a fault in the exhaust camshaft VVT solenoid circuit on bank 1. This solenoid controls exhaust valve timing for optimal performance and emissions.
Frequently Asked Questions
- What causes P0022?
- Most commonly dirty oil that restricts the VVT solenoid. An oil change often resolves it.
- Is P0022 expensive to fix?
- Usually not. An oil change ($30-$60) may fix it. If the VVT solenoid needs replacing, add $25-$90 for the part.
