DTC P0335 CKP SENSOR (POS)
Revision: 2004 November 2004 FX35/FX45
DTC P0335 CKP SENSOR (POS)PFP:23731
Component DescriptionABS006Q2
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.
CONSULT-II Reference Value in Data Monitor ModeABS006Q3
Specification data are reference values.
On Board Diagnosis LogicABS006Q4

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
running.
