P0335

COMPONENT DESCRIPTION
The crankshaft position sensor (POS) is located on the cylinder block rear housing facing the gear teeth (cogs) of the signal plate at the end of the crankshaft. 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 PCM receives the voltage signal and detects the fluctuation of the engine revolution.

On Board Diagnosis Logic:

DTC Confirmation Procedure

NOTE: If "DTC Confirmation Procedure" has been previously conducted, always turn ignition switch "OFF" and wait at least 10 seconds before conducting the next test.

TESTING CONDITION: Before performing the following procedure, confirm that the battery voltage is more than 10.5 V and the ignition switch is "ON".

With CONSULT-II
1. Turn ignition switch "ON" and select "DATA MONITOR" mode with CONSULT-II.




2. Crank engine for at least 2 seconds and run it for at least 5 seconds at idle speed.
3. If 1st trip DTC is detected, go to "Diagnostic Procedure" below.

With GST
Follow the procedure "With CONSULT-II".

DIAGNOSTIC PROCEDURE

COMPONENT INSPECTION




CRANKSHAFT POSITION SENSOR (POS)
1. Disconnect crankshaft position sensor (POS) harness connector.
2. Loosen the fixing bolt of the sensor.
3. Remove the sensor. Removal and Installation
4. Visually check the sensor for chipping.







5. Check resistance as shown in the figure.
If NG, replace crankshaft position sensor (POS).
