DTC P0327, P0328 KS

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 the ECM terminals, such as the ground.

Diagnostic Procedure

UBS00DJL

1. 

CHECK KNOCK SENSOR INPUT SIGNAL CIRCUIT FOR OPEN AND SHORT-I

1.

Turn ignition switch OFF.

2.

Disconnect ECM harness connector.

3.

Check resistance between ECM terminal 64 and engine ground.

NOTE:
It is necessary to use an ohmmeter which can measure more than 10 M

Ω.

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 FOR OPEN AND SHORT-II

1.

Disconnect knock sensor harness connector.

2.

Check harness continuity between ECM terminal 64 and knock sensor terminal 1. Refer to Wiring Dia-
gram.

3.

Also check harness for short to ground and short to power.

OK or NG

OK

>> GO TO 4.

NG

>> GO TO 3.

3. 

DETECT MALFUNCTIONING PART

Check the following.

●

Harness connector F37, F101

●

Harness for open or short between ECM and knock sensor

>> Repair open circuit or short to ground or short to power in harness or connectors.

CHECK KNOCK SENSOR

NOTE:
It is necessary to use an ohmmeter which can measure more than 10 M

Ω.

1.

Disconnect knock sensor harness connector.

2.

Check resistance between terminal 1 and ground.

CAUTION:

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

OK or NG

OK

>> GO TO 5.

NG

>> Replace knock sensor.

5. 

RETIGHTEN GROUND SCREWS

Loose and retighten engine ground screws.

>> GO TO 6.

6. 

CHECK INTERMITTENT INCIDENT

Refer to 

EC-696, "TROUBLE DIAGNOSIS FOR INTERMITTENT INCIDENT"

 .

DTC P0335 CKP SENSOR (OBD)

DTC P0335 CKP SENSOR (OBD)

PFP:23731

Component Description

UBS00DJM

The crankshaft position sensor (OBD) is located on the transmission
housing facing the gear teeth (cogs) of the flywheel or drive plate. It
detects the fluctuation of the engine revolution.
The sensor consists of a permanent magnet, core and coil.
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.
This sensor is not used to control the engine system. It is used only
for the on board diagnosis.

DTC Confirmation Procedure

UBS00DJP

NOTE:
If DTC Confirmation Procedure has been previously conducted, always turn ignition switch OFF and wait at
least 5 seconds before conducting the next test.

 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 15 seconds at idle speed.

3.

If 1st trip DTC is detected, go to 

EC-865, "Diagnostic Procedure"

.
