DTC P0336 CKP SENSORPFP:23731
DescriptionEBS01KGS
The crankshaft position (CKP) sensor is located on the cylinder
block rear housing facing the gear teeth (cogs) of the signal plate at
the end of the crankshaft. It detects the fluctuation of the engine rev-
olution.
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 ModeEBS01KGT
Specification data are reference values.
ECM Terminals and Reference ValueEBS01KGU
Specification data are reference values and are measured between each terminal and ground.
Pulse signal is measured by CONSULT-II.
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 ECM terminals, such as the ground.
: Average voltage for pulse signal (Actual pulse signal can be confirmed by oscilloscope.)

On Board Diagnosis Logic
EBS01KGV
NOTE:
If DTC P0336 is displayed with DTC P0652 or P0653, first perform the trouble diagnosis for DTC P0652
or P0653. Refer toEC-227, "
DTC P0652, P0653 SENSOR POWER SUPPLY".
DTC Confirmation ProcedureEBS01KGW
NOTE:
If DTC Confirmation Procedure has been previously conducted, always turn ignition switch OFF and wait at
least 10 seconds before conducting the next test.
WITH CONSULT-II
1. Turn ignition switch ON.
2. Select “DATA MONITOR” mode with CONSULT-II.
3. Start engine and let it idle for at least 5 seconds.
If engine can not start, keep ignition switch at START position for
5 seconds.
4. If DTC is detected, go toEC-168, "
Diagnostic Procedure".
WITHOUT CONSULT-II
1. Start engine and let it idle for at least 5 seconds.
If engine can not start, keep ignition switch at START position for 5 seconds.
2. Turn ignition switch OFF, wait at least 10 seconds and then turn ON.
3. Perform Diagnostic Test Mode II (Self-diagnostic results) with ECM.
4. If DTC is detected, go toEC-168, "
Diagnostic Procedure".
