CHECK HARNESS BETWEEN ECM AND BOOST 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 boost control valve connector.

Connector & terminal

(B134) No. 1 — (E64) 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 of harness between ECM connector and boost control valve connector

Poor contact of coupling connector
