DTC P1336 CKP SENSOR (OBD)
PFP:23731
Component Description
UBS00E0S
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.
On Board Diagnosis Logic

DTC Confirmation Procedure
UBS00E0U
NOTE:
If DTC Confirmation Procedure has been previously conducted, always turn ignition switch OFF and wait at
least 5 seconds before conducting the next test.
WITH CONSULT-II
1.
Turn ignition switch ON and select “DATA MONITOR” mode with
CONSULT-II.
2.
Start engine and run it for at least 2 minutes at idle speed.
3.
If 1st trip DTC is detected, go to
WITH GST
Follow the procedure “WITH CONSULT-II”.
