P0335 on Volkswagen: Causes, Symptoms and Fix Cost
Quick Answer
Critical SeverityNot safe to driveVolkswagen
P0335 on a Volkswagen means the engine control unit is not receiving a valid signal from the crankshaft position sensor. This sensor tells the ECU where the crankshaft is in its rotation, which is essential for fuel injection and ignition timing. Without it, the engine may not start or may stall unexpectedly. VW, Audi, Skoda and SEAT apps often show this code as P033500; the last two digits are a failure-type byte.

How to diagnose P0335 on a Volkswagen with OBD2
Follow these steps to pinpoint the root cause of P0335:
- Connect a scanner and check for the P0335 code along with any companion codes such as P0336 (range/performance) or P0340 (camshaft sensor)
- Inspect the crankshaft position sensor connector for corrosion, oil contamination, or loose pins. Clean and re-seat the connector
- Test the sensor output with a multimeter. For a Hall-effect sensor, check for 5V reference, ground, and signal. For a magnetic sensor, measure resistance (typically 200-2000 ohms depending on the make)
- Inspect the wiring harness from the sensor to the ECU for chafing, breaks, or heat damage. Pay attention to areas near the exhaust
- If the sensor and wiring test good, inspect the reluctor ring on the crankshaft pulley for missing teeth, cracks, or debris
