DTC P0335 CKP SENSOR (OBD)
PFP:23731
Component Description
UBS00D65
The crankshaft position sensor (OBD) is located on the transaxle
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 directly used to control the engine system. It is
used only for the on board diagnosis.

Possible cause
P0335
Crankshaft position
sensor (POS) circuit
●
The crankshaft position sensor (OBD) signal
is not detected by the ECM during the first
few seconds of engine cranking.
●
The proper pulse signal from the crankshaft
position sensor (OBD) is not sent to ECM
while the engine is running.
●
The crankshaft position sensor (OBD) signal
is not in the normal pattern during engine
running.
●
Harness or connectors
(The crankshaft position sensor (OBD)
circuit is open)

DTC P0335 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 ECM terminals, such as the ground.
: Average voltage for pulse signal (Actual pulse signal can be confirmed by oscilloscope.)
Diagnostic Procedure
UBS00D69
1.
RETIGHTEN GROUND SCREWS
1.
Turn ignition switch OFF.
2.
Loosen and retighten engine ground screws.
>> GO TO 2.
2.
CHECK INPUT SIGNAL CIRCUIT
1.
Disconnect crankshaft position sensor (OBD) and ECM harness
connectors.
2.
Disconnect ECM harness connector.
3.
Check continuity between ECM terminal 47 and crankshaft posi-
tion sensor (OBD) terminal 2.
Refer to Wiring Diagram.
4.
Also check harness for short to ground and short to power.
