OBD Code P0022

“A” Camshaft Position – Timing Over-Retarded

What’s mean?

OBD2 Code P0022 Definition:
A code P0022 Definition:the VVT (variable valve timing) or VCT (variable camshaft timing) components and the car’s PCM (powertrain control module, also called an ECM). That consists of a few different components but the P0022 DTC specifically Definition:the camshaft (cam) timing. In this case, if the cam timing is over-retarded, the engine light will be illluminated and the code will be set. The “A” camshaft is either the intake, left, or front camshaft.

Symptoms

Possible sumptoms of P0022
hard starting
poor idle and/or
stalling
There are potentially other symptoms as well. Of course, when trouble codes are set, the MIL (malfunction indicator lamp, a.k.a. the check engine light) illuminates.

Possible Causes

Possible causes of P0022
Incorrect camshaft timing
Wiring problems (harness/wiring) in intake timing control valve control solenoid system
Continuous oil flow to VCT piston chamber
Failed timing valve control solenoid (stuck open)

Possible Solutions

The main thing to check is to verify the operation of the VCT solenoid. You’re looking for a sticking or stuck VCt solenoid valve caused by contamination. Refer to vehicle specific repair manual to perform component tests for the VCT unit. Notes: Dealer techs have advanced tools and the ability to follow detailed troubleshooting steps, including the ability to test components using a scan tool.
