P0335 Crankshaft Position Sensor "A" Circuit
Engine timing
P0335 means the engine computer isn't getting a usable crankshaft position sensor signal, which can cause stalling or a no-start.
The crankshaft position sensor tells the engine computer the crankshaft's speed and position, which it needs for spark and fuel timing. P0335 means the computer isn't getting a usable signal from that sensor.
The engine may stall without warning or not start, so be careful: stalling in traffic is dangerous. Get it fixed before relying on the vehicle.
Common causes
- A failed crankshaft position sensor (common, often heat-related)
- Damaged wiring or a loose or corroded connector
- A damaged reluctor (tone) ring or debris on the sensor tip
- Excess gap between the sensor and the reluctor ring
Symptoms
- Engine cranks but won't start
- Stalling, especially when hot, sometimes restarting after it cools
- Misfires or rough running
- No tachometer reading while cranking on some vehicles
Common on: Nissan Altima, Nissan Rogue, Nissan Sentra
Known problems: Nissan 2.5L crankshaft and camshaft sensor stalling
What to check first
- Check the sensor's connector and wiring for damage, oil soaking or corrosion.
- Watch the RPM reading on a scan tool (or the tachometer) while cranking: zero RPM while cranking points to the crank sensor circuit.
- Check the sensor for metal debris on its tip.
- Test the sensor and its power and ground as your service information describes, and use a quality replacement: cheap crank sensors are a common cause of repeat failures.
