engine threw a P0022 code today... what does it mean?

[Dallas Starr]

Had a rough start today and then the check engnie light came on, scanned through my scangauge and realized the engine was throwing out a P0022 code. What is this code and what could be a cause or a solution.



My alternator is on the way out (could be related) but its getting replaced right away.

P0022....'A' Camshaft Position - Timing Over-Retarded (Bank 2)

so my timing is off?

From our FAQ section...

Cam timing improperly set

Continuous oil flow to the VCT piston chamber

VCT solenoid valve stuck open

Camshaft advance mechanism binding (VCT unit)

DTC P0022 is a check of the VCT unit. Engine will idle rough, hard starting and may stall. Diagnostics and repair for the VCT unit are located in the Workshop Manual. Check the operation of the VCT solenoid and check for a stuck or sticking solenoid valve caused by contamination. If the valve is stuck, check spider bracket for contamination prior to solenoid replacement.
