Repair Importance Level: 3/3
Repair Difficulty Level: 2/3  What does this mean?

P0335 Possible Causes

  • Faulty crankshaft position sensor
  • Crankshaft position sensor harness is open or shorted
  • Crankshaft position sensor circuit poor electrical connection
  • Signal plate may be damage
  • Starter motor may be faulty
  • Starting system circuit
  • Dead or weak battery

First diagnose P0335 code

    Check the "Possible Causes" listed above. Visually inspect the related wiring harness and connectors. Check for damaged components and look for broken, bent, pushed out, or corroded terminals.

P0335 Tech Notes

Sometimes and in some models, low battery voltage or a weak starter can trigger a Crankshaft Position Sensor code. Before replacing any parts, recharge or replaced battery.

Cost of diagnosing the P0335 code

    Labor: 1.0

    The cost of diagnosing the P0335 code is 1.0 hour of labor. The auto repair labor rates vary widely across the country, and even within the same city. Most auto repairs shops charge between $75 and $150 per hour.

When is the P0335 code detected?

The crankshaft position sensor (POS) signal is not detected by the Electronic Control Module (ECM) during the first few seconds of engine cranking

P0335 Possible Symptoms

  • Engine Light ON (or Service Engine Soon Warning Light)
  • Possible lack/loss of Power
  • Engine may stall while driving

P0335 Meaning

The Crankshaft Position Sensor (CKP) also known as the crank position sensor is an electronic device used in an engine to record the rate at which the crankshaft is spinning. This information is used by the Electronic Control Module(ECM) to control ignition and fuel injection. The sensor system consists of a rotating part, typically a disc, as well as a static part, the actual sensor.

When the engine is running, the high and low parts of the teeth cause the gap with the sensor to change. The changing gap causes the magnetic field near the sensor to change. The change in the magnetic field cause the voltage from the sensor to change.
