DTC P0335 CKP SENSOR (POS)

PFP:23731

Component Description

NBS000S1

The crankshaft position sensor (POS) is located on the oil pan facing
the gear teeth (cogs) of the signal plate. It detects the fluctuation of
the engine revolution.
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.
ECM receives the signals as shown in the figure.

●

The crankshaft position sensor (POS) signal
is not detected by the ECM during the first
few seconds of engine cranking.

●

The proper pulse signal from the crankshaft
position sensor (POS) is not sent to ECM
while the engine is running.

●

The crankshaft position sensor (POS) signal
is not in the normal pattern during engine
running.

DTC Confirmation Procedure

NBS000S4

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.
TESTING CONDITION:
Before performing the following procedure, confirm that battery voltage is more than 10.5V with igni-
tion switch ON.

WITH CONSULT-II

1.

Turn ignition switch ON and select “DATA MONITOR” mode with
CONSULT-II.

2.

Crank engine for at least 2 seconds and run it for at least 5 sec-
onds at idle speed.

3.

If 1st trip DTC is detected, go to

EC-378, "Diagnostic Procedure"

.

WITH GST

Follow the procedure “WITH CONSULT-II” above.
