Common causes, ranked by likelihood
Based on typical diagnoses for P0335. Work from the most likely cause down before replacing expensive parts.
Faulty crankshaft position sensor 45%
Damaged wiring or connector 25%
Metal debris on the sensor or reluctor ring 15%
Damaged reluctor / tone ring 10%
PCM or reference circuit fault 5%
How to diagnose it
- Inspect the crankshaft sensor connector and wiring for damage, oil contamination, or corrosion.
- Check for metal shavings on the sensor tip and clean if present.
- Test the sensor's signal with a scan tool while cranking, or measure resistance against spec.
- Inspect the reluctor ring for damaged teeth if the signal is erratic.
- Replace the sensor if it fails testing.

Nissan
Crank and cam sensor failures are common on several Nissan engines and can cause intermittent no-starts when hot.
P0335 questions, answered
Can I drive with P0335?
Be cautious. The car may run now but can stall or refuse to start without warning, since the engine relies on this sensor for timing. Repair it soon to avoid being stranded.
What are the symptoms of a bad crankshaft sensor?
Hard starting or no-start, intermittent stalling, rough running, and an erratic tachometer are the classic signs of a failing crankshaft position sensor.
