Symptoms
- Engine won't start or stalls unexpectedly
- Check Engine Light on
- Engine cranks but will not fire
- Intermittent stalling at speed
Typical fixes
- Replace crankshaft position sensor
- Inspect and repair wiring harness and connector
- Check tone ring for damage or packed debris
Repair cost range
Repairs for P0335 often fall between $100 and $350, depending on the cause and your vehicle.
