P0022 Intake Camshaft Position Timing Over-Retarded Bank 2

P0022 means the intake camshaft timing on bank 2 is more retarded than expected. The cam did not reach or hold the timing target requested by the module.

Code details

Generic OBD-II · P0

System: Fuel / Air
Code type: Generic (SAE / ISO controlled)
Standard: SAE J2012 / ISO 15031-6

Diagnostic boundary

A diagnostic trouble code reports that a monitored test failed. It does not prove one specific part is bad, and manufacturer logic can add vehicle-specific conditions.

Do not replace the camshaft position sensor just because cam timing is wrong; control, oil-flow, or mechanical timing faults are common.

Symptoms of P0022

Check-engine light on, sometimes with rough or uneven running.
Hesitation, surging, or a noticeable change in fuel economy.
Occasionally hard starting or a smell of unburnt fuel.

Common causes of P0022

A failing or contaminated sensor (MAF, MAP, oxygen or air-fuel sensor).
Intake or vacuum leaks, or an exhaust leak near an upstream sensor.
Wiring, connector, or fuel-delivery problems that skew the reading.

Useful checks before replacing parts

Check oil level, oil condition, and correct viscosity before deeper variable valve timing diagnosis.
Review commanded versus actual bank 2 intake cam position while watching for slow or stuck movement.
Inspect actuator wiring, solenoid response, restricted oil passages, timing-chain stretch, and phaser behavior.
