P0335 CKP SENSOR (POS)

Description

INFOID:0000000001089380

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.
ECM receives the signals as shown in the figure.

DTC CONFIRMATION PROCEDURE

1.

PRECONDITIONING

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 10.5V with igni-
tion switch ON.

>> GO TO 2.

2.

PERFORM DTC CONFIRMATION PROCEDURE

Possible cause

P0335

Crankshaft position sen-
sor (POS) circuit

• 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 run-
ning.

• Harness or connectors

[Crankshaft position sensor (POS) circuit 
is open or shorted.]
(Refrigerant pressure sensor circuit is 
shorted.)
(Accelerator pedal position sensor circuit 
is shorted.)

• Crankshaft position sensor (POS)
• Refrigerant pressure sensor
• Accelerator pedal position sensor
• Signal plate
