CHECK HARNESS BETWEEN ECM AND FUEL INJECTOR CONNECTOR.

1) Turn the ignition switch to OFF.

2) Disconnect the connectors from the ECM.

3) Measure the resistance of harness between ECM connector and fuel injector connector.

Connector & terminal

#1 (B137) No. 8 — (E5) No. 1:

#2 (B137) No. 9 — (E16) No. 1:

#3 (B137) No. 10 — (E6) No. 1:

#4 (B137) No. 11 — (E17) 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 of harness between ECM connector and fuel injector connector

Poor contact of coupling connector
