| CHECK HARNESS BETWEEN ECM AND COMMON RAIL PRESSURE SENSOR CONNECTOR. |
|
1) Turn the ignition switch to OFF. 2) Disconnect the connector from ECM and the common rail pressure sensor. 3) Measure the resistance of harness between ECM connector and common rail pressure sensor connector. Connector & terminal (B134) No. 76 — (E126) No. 1: (B134) No. 46 — (E126) No. 2: |
| 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 in harness between ECM connector and common rail pressure sensor connector • Poor contact of coupling connector |
