Crankshaft/Camshaft Sensor Range/Performance
2000-2003 Ford Excursion 7.3L V8 Power Stroke Diesel
Description
The PCM has detected a synchronization or erratic signal from the crankshaft position (CKP) or camshaft position (CMP) sensors. The signals do not correlate properly, indicating potential timing issues.
Symptoms
- Check Engine Light
- Engine misfires
- Rough idle
- Poor acceleration
- Stalling
- Difficulty starting
Common Causes
- Faulty crankshaft position sensor
- Faulty camshaft position sensor
- Damaged reluctor/tone ring
- Timing chain stretched or jumped (common on 4.0L SOHC)
- Faulty starter motor affecting signal
- Wiring damage
Diagnostic Steps
- Test CKP and CMP sensor signals on oscilloscope
- Inspect sensor gap and reluctor ring
- Check timing chain condition — especially on 4.0L SOHC
- Inspect sensor wiring and connectors
- Verify battery and starter motor condition
Repair Notes
Replace faulty sensor. On 4.0L SOHC, inspect timing chain guides — a broken chain guide is a known failure.
