A Camshaft Position - Timing Over Retarded (Bank 2)
The camshaft timing for bank 2 is too far retarded compared to the crankshaft.
Heads up: this code wasn't in our hand-written library yet, so DiagCoach AI built this page on the fly. Double-check critical specs against service info before condemning parts.
What it means (plain English)
The engine's computer expected the camshaft for bank 2 to be at a certain position, but it's lagging behind, which can affect engine performance and efficiency.
What the computer is actually seeing
The engine control module (ECM) monitors camshaft position sensors and determines if the timing is within expected range. If the timing is too delayed, it sets the P0022 code.
What a healthy reading looks like
Camshaft position signals should fluctuate within a range of 0-5 volts, with a typical operating range around 2-4 volts at idle. Timing should ideally match specifications outlined in the service manual.
Guided diagnostic — the DiagCoach way
Don't just throw parts at it. Walk through these in order — each step tells you whether to keep going or stop and fix what you found.
- 1Check engine oil level and condition; low or dirty oil can affect VVT operation. Ensure oil is at proper level and is clean. Decision: if oil is bad, change oil and retest. If oil is good, proceed to next step.
- 2Inspect wiring and connectors for the camshaft position sensor and VVT solenoid; look for frays, breaks, or corrosion. Decision: repair any wiring issues found and retest. If no issues found, go to next step.
- 3Using a scan tool, check the actual camshaft position compared to the desired position while monitoring engine RPM. Decision: if they differ significantly, suspect a faulty camshaft position sensor or timing issue. If they are within range, check the VVT solenoid operation and replace if needed.
Common causes
- Faulty camshaft position sensor
- Timing chain/belt slack or damage
- Variable valve timing (VVT) solenoid malfunction
- Oil flow issues affecting VVT operation
- Wiring or connector issues in the VVT system
