Check resistance between terminal 1 and ground.
CAUTION:
Do not use any knock sensors that have been dropped or phys-
ically damaged. Use only new ones.

DTC P0335 CKP SENSOR (OBD)
DTC P0335 CKP SENSOR (OBD)
PFP:23731
Component Description
UBS00DWZ
The crankshaft position sensor (OBD) is located on the transmission
housing facing the gear teeth (cogs) of the flywheel or drive plate. It
detects the fluctuation of the engine revolution.
The sensor consists of a permanent magnet, core and coil.
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.
This sensor is not used to control the engine system. It is used only
for the on board diagnosis.
