DTC P0327, P0328 KSPFP:22060
Component DescriptionEBS010ZA
The knock sensor is attached to the cylinder block. It senses engine knocking using a piezoelectric element. A
knocking vibration from the cylinder block is sensed as vibrational pressure. This pressure is converted into a
voltage signal and sent to the ECM.
On Board Diagnosis LogicEBS010ZB
The MI will not light up for these self-diagnoses.
DTC Confirmation ProcedureEBS010ZC
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 10V at idle.
WITH CONSULT-II
1. Turn ignition switch ON and select “DATA MONITOR” mode with
CONSULT-II.
2. Start engine and run it for at least 5 seconds at idle speed.
3. If 1st trip DTC is detected, go to EC-635, "
Diagnostic Procedure"
.
WITHOUT CONSULT-II
1. Start engine and run it for at least 5 seconds at idle speed.
2. Turn ignition switch OFF, wait at least 10 seconds and then turn ON.
3. Perform Diagnostic Test Mode II (Self-diagnostic results) with ECM.
4. If 1st trip DTC is detected, go to EC-635, "
Diagnostic Procedure" .

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 MΩ.
CAUTION:
Do not use any knock sensors that have been dropped or phys-
ically damaged. Use only new ones.

DTC P0335 CKP SENSOR (POS)

DTC P0335 CKP SENSOR (POS)PFP:23731
Component DescriptionEBS010ZH
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 ModeEBS010ZI
Specification data are reference values.
On Board Diagnosis LogicEBS010ZJ
DTC Confirmation ProcedureEBS010ZK
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, "

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.
