What Does Vauxhall Fault Code P0335 Mean?

Fault code P0335 is logged when the engine control unit (ECU) detects an irregular or missing signal from the crankshaft position sensor (CKP). This sensor is critical for engine timing, fuel injection, and ignition.

Common Vauxhall Models Affected

  • Vauxhall Astra
  • Vauxhall Corsa
  • Vauxhall Insignia
  • Vauxhall Zafira
  • All petrol and diesel engines using CKP sensors

Common Causes

  • Failed crankshaft position sensor
  • Damaged wiring or connector corrosion
  • Engine timing issues or reluctor ring damage
  • ECU sensor input circuit fault
  • Debris or metal shavings interfering with sensor signal

Typical Symptoms

  • Engine warning light illuminated
  • Engine will not start or cranks but does not fire
  • Intermittent stalling or misfire
  • Limp mode activation
  • P0335 reappears after clearing codes

How We Repair P0335

Blindly replacing the sensor does not always fix the issue. We test the CKP sensor signal under load, inspect wiring and connectors, verify the reluctor ring and timing, and check ECU input. Only the faulty component is replaced or repaired, ensuring reliable operation.
