DTC P0328: Knock/Combustion Vibration Sensor 1 Circuit High Bank 1 Or Single Sensor: Notes
DTC detecting condition:
Immediately at fault recognition
Trouble symptom:
- Poor driving performance
- Knocking occurs
CAUTION:
After servicing or replacing faulty parts, perform Clear Memory Mode Refer to ENGINE (DIAGNOSTICS) (STI)>CLEAR MEMORY MODE>OPERATION
., and inspection mode Refer to ENGINE (DIAGNOSTICS) (STI)>INSPECTION MODE>PROCEDURE
.
Wiring diagram:
Engine Electrical System Refer to WIRING SYSTEM>ENGINE ELECTRICAL SYSTEM>WIRING DIAGRAM .
- CHECK HARNESS BETWEEN ECM AND KNOCK SENSOR CONNECTOR.
- Turn the ignition switch to OFF.
- Disconnect the connector from ECM.
- Measure the resistance between ECM connectors.
Connector & terminal
(B137) No. 2 - (B134) No. 29:
Is the resistance 600 kΩ or more?
Yes: Go to 2.
No: Repair the poor contact of ECM connector.
- CHECK KNOCK SENSOR.
- Disconnect the connector from the knock sensor.
- Measure the resistance between knock sensor terminals.
Terminals
No. 1 - No. 2:
Is the resistance 600 kΩ or more?
Yes: Replace the knock sensor. Refer to FUEL INJECTION (FUEL SYSTEMS) (STI)>KNOCK SENSOR .
No: Repair the harness and connector.
NOTE: In this case, repair the following item:- Open circuit in harness between ECM connector and knock sensor connector
- Poor contact of knock sensor connector
- Poor contact of coupling connector
