| Official meaning | A Camshaft Position – Timing Over-Retarded (Bank 2) |
Bank 2 intake cam timing is over-retarded versus commanded. The phaser is failing to advance to the requested position on bank 2.

P0022 Quick Answer
Bank 2 intake cam timing is over-retarded versus commanded. The phaser is failing to advance to the requested position on bank 2. The first thing to check is engine oil level, condition, and viscosity — many P002-range faults are oil-driven before they are electrical.
What Does P0022 Mean?
A Camshaft Position – Timing Over-Retarded (Bank 2). Bank 2 intake cam timing is over-retarded versus commanded. The phaser is failing to advance to the requested position on bank 2.
Symptoms
- Check engine light
- Rough or unstable idle
- Sluggish acceleration
- Reduced fuel economy
Common Causes
- Low oil pressure at the bank 2 VVT supply
- Stuck-closed bank 2 intake VVT solenoid
- Sludge in the bank 2 phaser
- Stretched bank 2 timing chain
- Failed bank 2 cam phaser
Diagnosis Steps
You’ll need a scan tool capable of reading live powertrain data, a digital multimeter, and access to the wiring diagram for the specific platform.
- Confirm oil level and pressure (measure at a port if available).
- Compare commanded vs actual bank 2 cam phase across rpm.
- Inspect VVT solenoid and clean / replace.
- Check chain stretch on bank 2.
Possible Fixes
- Bank 2 VVT solenoid replacement
- Oil service
- Timing chain kit on bank 2
- Phaser replacement
Can I Still Drive With P0022?
The vehicle will usually still drive with P0022 stored, but performance and fuel economy are degraded. The fault disables or limits the affected actuator, and the PCM may inhibit emissions monitors. Drive to a workshop, but don’t ignore the code long-term — VVT and EVAP failures often cascade into related faults if left untreated.
How Serious Is This Code?
P0022 is a moderate-priority fault. It will not prevent the engine from running but will affect drivability, emissions, and over time can damage related components (cam phaser wear, catalytic converter on EVAP-related codes). Address within a few drive cycles.
FAQ
Will P0022 clear itself?
Only if the underlying fault was intermittent and self-corrected. Most P0022 root causes (failed solenoid, wiring damage, blocked screen) are persistent and require physical repair.
Can I clear P0022 without fixing it?
You can clear it with a scan tool, but it will return as soon as the fault condition reappears — typically within one or two drive cycles.
Is P0022 related to other codes?
Often, yes. Cam-position and EVAP faults frequently set adjacent codes — if P0022 is present, scan for related codes in the same range and address them as a group rather than one at a time.
