| CHECK HARNESS BETWEEN ENGINE COOLANT TEMPERATURE SENSOR AND ECM CONNECTOR. |
|
1) Turn the ignition switch to OFF. 2) Measure the resistance of harness between engine coolant temperature sensor connector and engine ground. Connector & terminal (E8) No. 1 — Engine ground: |
| QUESTION | |
|
Is the resistance less than 5 Ω? | |
| Yes | No |
|
Replace the engine coolant temperature sensor. |
Repair the harness and connector. NOTE: In this case, repair the following item: • Open circuit of harness between ECM and engine coolant temperature sensor connector • Poor contact of engine coolant temperature sensor connector • Poor contact in ECM connector • Poor contact of coupling connector |
