P0022Powertrain
Intake camshaft timing (bank 2) — over-retarded
Where to start
The second bank's timing is retarded from the target. Check the oil and the phaser's filter screen — it clogs first.
A code is not a diagnosis. It says which check failed, not which part to replace. Clearing it without repair only means the car will report it again in a few trips.

CarScan reads this code from your car through an OBD-II adapter, shows whether it is active now or only stored, names the module that reported it, and puts it into a plain-text report for your mechanic.
