DTC: P0335

Search Bulletins/Recalls for P0335

Trouble diagnosis name: Crankshaft position sensor (POS) circuit

Shape may vary for some models

Component Description

The crankshaft position sensor (POS) is located on the oil pan facing the gear teeth (cogs) of the signal plate. It detects the fluctuation of the engine revolution.

The sensor consists of a permanent magnet and Hall IC. 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.

Due to the changing magnetic field, the voltage from the sensor changes.

The ECM receives the voltage signal and detects the fluctuation of the engine revolution.

DTC detecting condition:

• The crankshaft position sensor (POS) signal is not detected by the ECM during the first few seconds of engine cranking
• The proper pulse signal from the crankshaft position sensor (POS) is not sent to ECM while the engine is running.
• The crankshaft position sensor (POS) signal is not in the normal pattern during engine running.

Possible cause:

• Harness or connectors (The sensor circuit is open or shorted)
• Crankshaft position sensor (POS) may be faulty
• Signal plate may be damage
