CHECK HARNESS BETWEEN FUEL INJECTOR AND ECM CONNECTOR.

Measure the resistance of harness connector between ECM connector and fuel injector on faulty cylinders.

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 and fuel injector connector

Poor contact of coupling connector
