STEPCHECKYESNO

1.CHECK HARNESS BETWEEN ECM AND KNOCK SENSOR CONNECTOR.

1) Turn the ignition switch to OFF.

2) Disconnect the connector from ECM.

3) Measure the resistance between ECM connectors.

Connector & terminal

(E158) No. 30 — (E158) No. 34:

Is the resistance 600 k- or more-

Diagnostic Procedure with Diagnostic Trouble Code (DTC) > DTC P0328 KNOCK/COMBUSTION VIBRATION SENSOR 1 CIRCUIT HIGH BANK 1 OR SINGLE SENSOR

Repair the poor contact of ECM connector.

2.CHECK KNOCK SENSOR.

1) Disconnect the connector from the knock sensor.

2) Measure the resistance between knock sensor terminals.

Terminals

No. 1 — No. 2:

Is the resistance 600 k- or more-
