P0335: Crankshaft Position Sensor Circuit Malfunction
Can you still drive? No. If the crankshaft position sensor has failed, the engine will not run. Have the vehicle towed to a repair facility.
What Does P0335 Mean?
Code P0335 indicates that the engine control module is not receiving a proper signal from the crankshaft position sensor. The crankshaft position sensor is critical for engine operation as it tells the ECM the position and rotational speed of the crankshaft. Without this signal, most engines will not start or will stall and not restart.
