P0335 CKP SENSOR (POS)
P0335 CKP SENSOR (POS)
Description
INFOID:0000000005536653
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.

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
[CKP sensor (POS) circuit is open or
shorted.]
(APP sensor 2 circuit is shorted.)
(EVAP control system pressure sensor
circuit is shorted.)
(Refrigerant pressure sensor circuit is
shorted.)
• Crankshaft position sensor (POS)
• Accelerator pedal position sensor
• EVAP control system pressure sensor
• Refrigerant pressure sensor
• Signal plate
