DTC P0328:00 [MZR 2.0 DISI i-stop]

id0102d4703100

DTC P0328:00

KS circuit high input
DETECTION CONDITION
•  The PCM monitors the input signal from the KS when the engine is running. If the input voltage at the PCM terminals between 2V and 2U is above 4.9 V, the PCM determines that the KS circuit has a malfunction.
Diagnostic support note
•  This is a continuous monitor (CCM).
•  The MIL illuminates if the PCM detects the above malfunction condition during the first drive cycle.
•  FREEZE FRAME DATA (Mode 2)/Snapshot data is available.
•  The DTC is stored in the PCM memory.
POSSIBLE CAUSE
•  KS connector or terminals malfunction
•  KS malfunction
•  PCM connector or terminals malfunction
•  Short to power supply in wiring harness between the following terminals:
―  KS terminal A—PCM terminal 2U
―  KS terminal B—PCM terminal 2V
•  PCM malfunction

Diagnostic procedure

STEP

INSPECTION

ACTION
1
VERIFY FREEZE FRAME DATA (MODE 2)/SNAPSHOT DATA HAS BEEN RECORDED
•  Has the FREEZE FRAME DATA (Mode 2)/snapshot data been recorded?
Yes
Go to the next step.
No
Record the FREEZE FRAME DATA (Mode 2)/snapshot data on the repair order, then go to the next step.
2
VERIFY RELATED SERVICE INFORMATION AVAILABILITY
•  Verify related Service Information availability.
•  Is any related Service Information available?
Yes
Perform repair or diagnosis according to the available Service Information.
•  If the vehicle is not repaired, go to the next step.
No
Go to the next step.
3
INSPECT KS CONNECTOR CONDITION
•  Switch the ignition to off.
•  Disconnect the KS connector.
•  Inspect for poor connection (such as damaged/pulled-out pins, corrosion).
•  Is there any malfunction?
Yes
Repair or replace the terminal and/or connector, then go to Step 7.
No
Go to the next step.
4
INSPECT KS
•  Inspect the KS.
•  Is there any malfunction?
Yes
Replace the KS, then go to Step 7.
(See KNOCK SENSOR (KS) REMOVAL/INSTALLATION [MZR 2.0 DISI i-stop].)
No
Go to the next step.
5
INSPECT PCM CONNECTOR CONDITION
•  Disconnect the PCM connector.
•  Inspect for poor connection (such as damaged/pulled-out pins, corrosion).
•  Is there any malfunction?
Yes
Repair or replace the terminal and/or connector, then go to Step 7.
No
Go to the next step.
6
INSPECT KS CIRCUIT FOR SHORT TO POWER SUPPLY
•  KS and PCM connectors are disconnected.
•  Switch the ignition to ON (engine off).
•  Measure the voltage at the following terminals (wiring harness-side):
―  KS terminal A
―  KS terminal B
•  Is there any voltage?
Yes
Repair or replace the wiring harness for a possible short to power supply, then go to the next step.
No
Go to the next step.
7
VERIFY DTC TROUBLESHOOTING COMPLETED
•  Make sure to reconnect all disconnected connectors.
•  Clear the DTC from the PCM memory using the M-MDS.
•  Start the engine and warm it up completely.
•  Perform the KOEO or KOER self test.
•  Is the same DTC present?
Yes
Repeat the inspection from Step 1.
•  If the malfunction recurs, replace the PCM.
Go to the next step.
No
Go to the next step.
8
VERIFY AFTER REPAIR PROCEDURE
•  Perform the “AFTER REPAIR PROCEDURE”.
•  Are any DTCs present?
Yes
Go to the applicable DTC inspection.
(See DTC TABLE [MZR 2.0 DISI i-stop].)
No
DTC troubleshooting completed.
