KNOCK SENSOR
Check resistance between knock sensor terminal 1 and ground.
NOTE:
It is necessary to use an ohmmeter which can measure more
than 10 M

DTC P0335 CKP SENSOR (POS)
PFP:23731
Component Description
EBS00QN9
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, 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

DTC Confirmation Procedure
EBS00QNC
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-345, "Diagnostic Procedure"
.
WITH GST
Follow the procedure “WITH CONSULT-II” above.

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.)

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.)
