What does P0335 mean?
The crankshaft position (CKP) sensor reads a toothed wheel on the crankshaft. The computer uses it for engine speed, spark and injection timing. Without it, most engines will not run.
The computer has detected an electrical fault in this sensor circuit.
Codes are a starting point. They tell you which test failed, not which part to replace. Check for other stored codes and fix those in a sensible order.
Symptoms
- Engine cranks but will not start
- Stalling, often when hot
- Intermittent loss of tach signal
- Misfires or rough running
Common causes
- Open or shorted wiring
- Corroded connector
- Failed sensor
How to diagnose P0335
- Inspect connector and harness.
- Check the signal with a meter or scope.
- Replace the sensor after wiring checks out.
- Check whether the tachometer moves while cranking. No movement often means no CKP signal.
- Inspect the sensor and connector for oil, damage and debris.
How to fix it
- Replace the crankshaft position sensor
- Repair wiring
- Repair the tone wheel
Estimated repair cost
Likely repairs for P0335 run from about $100 to $400, depending on the cause.
| Repair | Typical range (parts + labor) |
|---|---|
| Diagnostic fee (scan + testing) | $100 - $200 |
| Crankshaft position sensor | $120 - $350 |
| Wiring/connector repair | $100 - $400 |
These are rough US estimates for an independent shop in 2026, based on typical parts prices and standard labor times. Dealers, big trucks, luxury brands and high-cost areas often run higher. They are not quotes. Use the repair cost estimator to adjust for your vehicle.
How serious is P0335?
High severity
Not recommended. A failing crank sensor can kill the engine while you are driving.

Nissan
Some Nissan models have had recalls or service campaigns for crank and cam position sensors that could cause stalling. Check for open recalls by VIN before buying parts.
Always check open recalls and technical service bulletins for your VIN.
P0335 FAQ
Can a bad crankshaft sensor cause a no-start?
Yes. Without a crank signal, most engines will crank but not start.
Can I drive with P0335?
It is risky. The engine can stall without warning.
What does P0335 mean?
P0335 stands for "Crankshaft Position Sensor "A" Circuit". The crankshaft position (CKP) sensor reads a toothed wheel on the crankshaft.
How much does it cost to fix P0335?
It depends on the cause. The likely repairs for P0335 range from about $100 to $400 at an independent shop in the US, plus a diagnostic fee of roughly $100-$200. These are rough estimates; dealer prices and some vehicles run higher.
What is the most common cause of P0335?
The most common causes are: open or shorted wiring; corroded connector; failed sensor.
