DTC P1336 CKP SENSOR (OBD)
DTC P1336 CKP SENSOR (OBD)
PFP:23731
Component Description
UBS00DO1
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.

DTC Confirmation Procedure
UBS00DO3
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”.

DTC P1336 CKP SENSOR (OBD)
Specification data are reference values and are measured between each terminal and ground.
CAUTION:
Do not use ECM ground terminals when measuring input/output voltage. Doing so may result in dam-
age to the ECM's transistor. Use a ground other than the ECM terminals, such as the ground.
: Average voltage for pulse signal (Actual pulse signal can be confirmed by oscilloscope.)
Diagnostic Procedure
UBS00DO5
1.
RETIGHTEN GROUND SCREWS
1.
Turn ignition switch OFF.
2.
Loosen and retighten engine ground screws.
>> GO TO 2.
2.
CHECK CKP SENSOR (OBD) INPUT SIGNAL CIRCUIT FOR OPEN AND SHORT
1.
Disconnect crankshaft position sensor (OBD) and ECM harness
connectors.
2.
Check continuity between ECM terminal 47 and CKP sensor
(OBD) terminal 2.
3.
Also check harness for short to ground and short to power.
