P0335 — Crankshaft Position Sensor Circuit
STOPIs it safe to drive? The crank sensor tells the computer where the pistons are — without it the engine can stall or not start. Treat an intermittent one as urgent.
What P0335 means
The crankshaft position sensor signal is missing or out of range. It's the primary input for spark and fuel timing; a dropout means a stall.
Most likely causes (in order)
- Failed crank position sensor
- Wiring / connector (heat-related dropouts common)
- Damaged reluctor/tone ring
- Sensor air-gap or debris
Symptoms you might notice
- Stalling / no-start
- Hard hot-start
- Tachometer drops to zero while running
What to check first
Check the sensor signal cranking with a scope or meter; inspect wiring and the connector for heat damage. A no-start with a dead tach points right here.
