P0335 on Opel
Crankshaft Position Sensor A Circuit Malfunction
P0335 on Opel vehicles indicates crankshaft position sensor a circuit malfunction. Au7o has documented this code across 2 Opel models — most commonly on Mokka, Vivaro. This code means the engine computer has lost or detected a faulty signal from the crankshaft position sensor (sensor A), which tells the computer exactly how fast and in what position the crankshaft is rotating. That signal is essential for timing the spark and fuel injection, so a problem here can cause hard starting, stalling, or a no-start condition. The computer sets this code when the crank sensor signal is missing, erratic, or out of its expected pattern. Causes range from a failed sensor or damaged wiring to a problem with the reluctor (tone) ring the sensor reads. Typical repair costs on Opel range from $700 to $4,500, depending on the specific model and root cause.
Common Causes of P0335
- •Failed crankshaft position sensor
- •Damaged, corroded, or loose sensor wiring/connector
- •Metal debris or oil contamination on the sensor tip
- •Damaged or misaligned reluctor (tone) ring
- •Excessive air gap between sensor and tone ring
- •Wiring shorted or open in the sensor circuit
- •Faulty PCM/ECM (rare)
P0335 on Opel by Model
Opel Mokka(1 issue)
- Mokka A 1.7 CDTI Water Pump / Timing Belt Drive2012-2019
The 1.7 CDTI water pump is timing-belt-driven in this engine. When the pump seizes or its impeller fails, the timing belt can be ejected — leading to valve damage. Failure typically appears between 80,000-130,000 km, often before the recommended belt service.
Opel Vivaro(1 issue)
- Vivaro B 1.6 BiTurbo CDTI (R9M) Timing Chain Stretch2014-2019
The Renault-sourced R9M 1.6 BiTurbo CDTI used in Vivaro B (and Trafic III, Movano B) develops timing chain stretch, typically 100,000-180,000 km. Cold-start rattle, misfire codes, then potential chain skip causing valve damage. Particularly bad on stop-start fleet use without regular oil changes.
