Continuous Variable Valve Timing Control Exceeded Learning Limit
on 2011 Volvo XC60 3.2L I6 · AWD
What this code means
The continuous VVT system has exceeded its adaptive learning limits for cam timing correction. This indicates significant mechanical wear or drift.
Symptoms
- Check Engine Light
- Gradually worsening idle quality
- Increasing fuel consumption
- Timing chain rattle on cold start
- Loss of power progressing over time
Common causes
- Timing chain stretch exceeding tolerance
- Worn camshaft phaser
- Oil passage wear causing leakage
- VVT solenoid wear
- Significant engine mileage/wear
Diagnostic steps
- Check VVT learned values in scan tool
- Compare cam timing actual vs target
- Inspect timing chain for stretch
- Check phaser for wear
- Review oil change history
Repair notes
Timing chain and/or camshaft phaser replacement likely needed. This code indicates the system can no longer compensate for mechanical wear.
