| CHECK HARNESS BETWEEN KNOCK SENSOR AND ECM CONNECTOR. |
|
1) Disconnect the connector from knock sensor. 2) Measure the resistance between ECM and knock sensor connector. Connector & terminal (B137) No. 17 — (E14) No. 2: (B137) No. 31 — (E14) No. 1: |
| QUESTION | |
|
Is the resistance less than 1 Ω? | |
| Yes | No |
|
|
Repair the harness and connector. NOTE: In this case, repair the following item: • Open circuit of harness between knock sensor and ECM connector • Poor contact of knock sensor connector • Poor contact of coupling connector • Poor contact of joint connector |
