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.
Diagnostic ProcedureEBS010PQ
1. CHECK KNOCK SENSOR INPUT SIGNAL CIRCUIT-I
1. Turn ignition switch OFF.
2. Disconnect ECM harness connector.
3. Check resistance between ECM terminal 15 and ground. Refer to Wiring Diagram.
NOTE:
It is necessary to use an ohmmeter which can measure more than 10 MΩ.
4. Also check harness for short to ground and short to power.
OK or NG
OK >> GO TO 4.
NG >> GO TO 2.
2. CHECK KNOCK SENSOR INPUT SIGNAL CIRCUIT-II
1. Disconnect knock sensor harness connector.
2. Check harness continuity between ECM terminal 15 and knock sensor terminal 1.
Refer to Wiring Diagram.
3. Also check harness for short to ground and short to power.
OK or NG
OK >> GO TO 3.
NG >> Repair open circuit or short to ground or short to power in harness or connectors.

DTC P0335 CKP SENSOR (POS)PFP:23731
Component DescriptionEBS010PT
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 ModeEBS010PU
Specification data are reference values.
On Board Diagnosis LogicEBS010PV
DTC Confirmation ProcedureEBS010PW
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-250, "
Diagnostic Procedure"
.
WITH GST
Follow the procedure “WITH CONSULT-II” above.

0335Crankshaft 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.
