Causes ranked by likelihood
| Cause | Likelihood | DIY difficulty |
|---|---|---|
| Failed crankshaft position sensor — Heat-related failures are typical — it may run fine cold and quit when hot. | Most likely | 3/5 |
| Damaged reluctor ring or tone wheel — Cracked or debris-packed teeth produce a bad signal. | Possible | 3/5 |
| Wiring or connector fault — Check for oil intrusion in the connector. | Less likely | 3/5 |
| Metal debris on the sensor tip — Clean and reinstall before replacing. | Less likely | 3/5 |

- Check for companion codes. Look for other stored or pending codes such as P0336, P0340, P0016 — they often point to one shared root cause.
- Check: Metal debris on the sensor tip. Clean and reinstall before replacing.
- Check: Wiring or connector fault. Check for oil intrusion in the connector.
- Check: Failed crankshaft position sensor. Heat-related failures are typical — it may run fine cold and quit when hot.
- Check: Damaged reluctor ring or tone wheel. Cracked or debris-packed teeth produce a bad signal.
