CMP/CKP Sensor Signals Not Compatible
on 1996 Volvo 960 2.9L I6 · FWD
What this code means
The ECM detected that the camshaft position sensor and crankshaft position sensor signals are not in the expected correlation. The timing relationship between the two sensors is outside acceptable limits, indicating a potential timing issue.
Symptoms
- Check Engine Light
- Engine may not start
- Rough running
- Loss of power
- Misfires
Common causes
- Timing belt or chain jumped a tooth
- Faulty camshaft position sensor
- Faulty crankshaft position sensor
- Tone wheel damage on camshaft or crankshaft
- Timing belt tensioner failure
Diagnostic steps
- Check timing belt/chain alignment marks
- Test CMP sensor signal with oscilloscope
- Test CKP sensor signal
- Inspect timing belt/chain tensioner
- Compare CMP/CKP correlation pattern
Repair notes
Verify timing belt or chain alignment; replace sensors or timing components as needed.
