| CHECK HARNESS BETWEEN ECM AND EGR CONTROL VALVE CONNECTOR. |
|
1) Turn the ignition switch to OFF. 2) Disconnect the connector from ECM. 3) Measure the resistance of harness between ECM connector and EGR control valve connector. Connector & terminal (B134) No. 57 — (E18) No. 3: |
| QUESTION | |
|
Is the resistance less than 1 Ω? | |
| Yes | No |
|
Replace EGR control valve. |
Repair the harness and connector. NOTE: In this case, repair the following item: • Open circuit of harness between ECM connector and EGR control valve connector • Poor contact of coupling connector |
