Code P0335 Description

The P0335 diagnostic trouble code (DTC) indicates a malfunction in the circuit of the crankshaft position sensor 'A'. The crankshaft position sensor is a vital component in the engine management system, as it detects the position of the crankshaft and sends this information to the engine control module (ECM). This data is crucial for proper fuel injection timing, ignition timing, and overall engine performance. When the ECM receives erratic or no signal from the crankshaft position sensor, it can lead to various issues, such as misfiring, rough idling, stalling, and even engine failure.

  • Hi there really upset took corsa 2004 with 35.009 miles for a dianostics as engine management light was on. Code given was p0335. Told i need a new Clinder head, timing chain replaced and water pump. Dont know anything about cars. Could this be right. As far as i am aware my car is driving alright.

  • WHERE CAN I FIND A WIRING DIAGRAM....I HAVE A 2007 UPLANDER...SOME ONE PULLED THE WIRES OUT OF THE CRANK SHAFT POS. SENSOR CONNECTOR...I NEED TO KNOW WHICH COLOR WIRE GOES TO WHICH PIN

  • Here is the wire diagram from the service manual, I hope it helps

  • pls, where can i find the Crankshaft Position Sensor in my nissan primera 2005 within the engine?

  • Sparks every3 to 4 seconds???

  • 03 pt cruiser back fires after cranks for 3 minutes and sparks every 3 seconds and no start????

  • Po335 crank position sensor A circuit

  • You probably have to replace the sensor to repair the problem.

  • I have a 2005ptcruiser,codes came up,random misfire also both heater sensors,eng light came on flashing then just died no crank no start,I replaced plugs wires and cam shaft sensor about 6 months ago this car real dangerous just dies while driving usually at stop sign even when I put in nuteral,please help

  • You probably have to replace the crankshaft position sensor. Also, check the timing belt. Sometimes the timing belt brakes and cause the symptoms you describe. It's very common for your vehicle model year.
