P0022
Camshaft Timing Over-Retarded Bank 2
The engine computer has found that the intake camshaft on bank 2 is not moving to the correct timing position. This usually points to a problem with oil flow, the cam timing actuator, or the timing chain system. It can cause rough running, poor power, and engine warning lights.

Quick answer
AI-CITATION READYWhat it means
Can you drive with it?
Most common causes
- Low engine oil level, dirty oil, or wrong oil viscosity affecting VVT operation
- Faulty oil control valve / VVT solenoid on bank 2
- Sticking or failed cam phaser on bank 2
Typical repair cost
DIY usually runs $20–$200. Typical shop repair lands around $150–$900, depending on the root cause.
01 / Definition
P0022 means the PCM has detected that the camshaft timing on bank 2 is more retarded than commanded. On most engines this involves the intake camshaft, variable valve timing system, oil control valve, cam phaser, or mechanical timing components. The code is often set when the PCM cannot bring cam position into the expected range during operation or startup.
02 / Drive status
With caution. You may be able to drive short distances, but performance and fuel economy can be worse. If the engine runs rough, makes timing noise, or the check engine light flashes, stop driving and have it checked soon.
03 / Symptoms
- Check engine light
- Rough idle
- Poor acceleration
- Reduced fuel economy
- Hard starting
- Engine may hesitate or stall
- Possible rattling or ticking noise from timing area
- Failed emissions test
04 / Causes
| 1 | Low engine oil level, dirty oil, or wrong oil viscosity affecting VVT operation | high |
|---|---|---|
| 2 | Faulty oil control valve / VVT solenoid on bank 2 | high |
| 3 | Sticking or failed cam phaser on bank 2 | high |
| 4 | Camshaft position sensor or wiring problem on bank 2 | medium |
| 5 | Timing chain stretch, slipped timing, or worn timing components | medium |
| 6 | Restricted oil passages or sludge buildup in the engine | medium |
| 7 | PCM software issue or internal PCM fault | low |
05 / Diagnostic sequence
- 01Check engine oil level, condition, and correct viscosity.
- 02Scan for related codes such as camshaft sensor, crankshaft sensor, misfire, or oil control solenoid codes.
- 03Inspect wiring, connectors, and harness routing for the bank 2 cam sensor and VVT solenoid.
- 04Command the VVT solenoid with a scan tool and verify camshaft timing changes.
- 05Test the oil control valve for blockage, sticking, or electrical failure.
- 06Inspect cam phaser operation and listen for abnormal timing chain noise.
- 07Verify mechanical timing if the problem persists or if timing-related noise is present.
- 08Check for manufacturer technical service bulletins and PCM updates.
06 / Repairs
| 1 | Change engine oil and filter with the correct specification oil | $40–$120 |
|---|---|---|
| 2 | Clean or replace the bank 2 VVT solenoid / oil control valve | $60–$250 |
| 3 | Repair damaged wiring, connectors, or sensor circuits | $50–$300 |
| 4 | Replace the cam phaser if it is sticking or not responding correctly | $300–$900 |
| 5 | Repair timing chain, guides, tensioner, or related mechanical timing parts | $500–$2,000 |

08 / FAQ
What does bank 2 mean?
Bank 2 is the side of the engine that does not contain cylinder number 1.
Can bad oil cause P0022?
Yes. Dirty oil, low oil level, or the wrong oil can keep the VVT system from working properly.
Will a P0022 code clear itself?
It may go away temporarily if the problem is intermittent, but it usually returns until the cause is fixed.
Can a timing chain cause P0022?
Yes. A stretched or slipped timing chain can put cam timing out of range and trigger this code.
