P0335

COMPONENT DESCRIPTION
The crankshaft position sensor (POS) is located on the oil pan facing the gear teeth (cogs) of the signal plate (flywheel). It detects the crankshaft position signal (1 ° signal).

The sensor consists of a permanent magnet, core and coil.

When engine is running, the gap between the sensor and the gear teeth (cogs) will periodically change. Permeability near the sensor also changes.

Due to the permeability change, the magnetic flux near the core is changed. Therefore, the voltage signal generated in the coil is changed.

The ECM receives the voltage signal and detects the crankshaft position signal (1 ° signal).

Specification Data Are Reference Values:

ON BOARD DIAGNOSIS LOGIC
Malfunction is detected when 1 ° signal is not entered to ECM for the first few seconds during engine cranking, or 1 ° signal is not entered to ECM during engine running.

Possible Cause
- Harness or connectors
(The crankshaft position sensor (POS) circuit is open or shorted.)
- Crankshaft position sensor (POS)
- Starter motor
- Starting system circuit
- Dead (Weak) battery

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 battery voltage is more than 10.5 V.

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

2. Crank engine for at least two seconds.
3. If 1st trip DTC is detected, go to "Diagnostic Procedure" below.

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