P0335 CKP SENSOR (POS)
P0335 CKP SENSOR (POS)
Description
INFOID:0000000001096850
The crankshaft position sensor (POS) is located on the cylinder
block rear housing facing the gear teeth (cogs) of the signal plate at
end of the crankshaft. It detects the fluctuation of the engine revolu-
tion.
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
1.
Start engine and let it idle for at least 5 seconds.
If engine does not start, crank engine for at least 2 seconds.

DTC detecting condition
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
