CHECK HARNESS BETWEEN ECM AND INTAKE CAMSHAFT POSITION SENSOR CONNECTOR.

1) Turn the ignition switch to OFF.

2) Disconnect the connectors from the ECM.

3) Measure the resistance between the ECM and intake camshaft position sensor connector.

Connector & terminal

(B137) No. 13 — (E35) No. 2:

(B134) No. 29 — (E35) No. 3:

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 the harness between the ECM and intake camshaft position sensor connector

Poor contact of coupling connector
