CHECK HARNESS BETWEEN ECM AND OIL TEMPERATURE SENSOR CONNECTOR.

1) Turn the ignition switch to OFF.

2) Disconnect the connector from the ECM and oil temperature sensor.

3) Measure the resistance of the harness between the ECM and oil temperature sensor connector.

Connector & terminal

(B134) No. 23 — (E75) No. 2:

(B134) No. 29 — (E75) 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 in harness between ECM and oil temperature sensor connector

Poor contact of coupling connector
