DTC P0336 CKP SENSORPFP:23731
DescriptionEBS011B3
The crankshaft position sensor monitors engine speed by means of
signals from the sensing plate (with 56 protrusions) installed to the
fly wheel. The datum signal output is detected 6° signal and sent to
the ECM. The sensor signal is used for fuel injection control and fuel
injection timing control.
CONSULT-II Reference Value in Data Monitor ModeEBS011B4
Specification data are reference values.
On Board Diagnosis LogicEBS011B6
NOTE:

If DTC P0336 is displayed with DTC P0652 or P0653, first perform trouble diagnosis for DTC P0652
or P0653. Refer to EC-1240, "
DTC P0652, P0653 SENSOR POWER SUPPLY" .
DTC Confirmation ProcedureEBS011B7
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 could not start, keep ignition switch at START position
for 5 seconds.
4. If 1st trip DTC is detected, go to EC-1166, "
Diagnostic Proce-
dure" .
WITH GST
Follow the procedure “WITH CONSULT-II” above.

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.
