P0336 — Crankshaft Position Sensor "A" Circuit Range/Performance
The CKP signal is present but inconsistent with engine RPM, or pulse counts deviate from the reluctor's expected pattern. Often points to a damaged tooth on the reluctor or an air gap that has changed.
General code reference. Confirm the definition and diagnostic procedure for your vehicle's year, model and engine. A stored code alone does not identify a failed part.

- Reluctor ring
Possible causes to check
These are possible checks, not a ranked diagnosis. Follow the vehicle manufacturer's test procedure before replacing parts.
- Reluctor tooth damaged
- Sensor air gap incorrect
