DTC P0335 CKP SENSOR (POS)
DTC P0335 CKP SENSOR (POS) PFP:23731
Component Description EBS010ZH
The crankshaft position sensor (POS) 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 to 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 Mode EBS010ZI
Specification data are reference values.
On Board Diagnosis Logic EBS010ZJ
DTC Confirmation Procedure EBS010ZK
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-642, "
Diagnostic Procedure"
.

Crankshaft position
sensor (POS) circuit
● 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.
● Harness or connectors
(The sensor circuit is open or
shorted.)
● Crankshaft position sensor (POS)
● Signal plate
