Typical example of the connector on the valve mechanism cover

Test Step 1. Inspect Electrical Connectors

and Wiring

Electrical shock hazard. The electronic unit injec-

tor system uses 67-73 volts.

Turn the keyswitch to the OFF position. A strong

electrical shock hazard is present if the keyswitch

is not turned OFF.

Thoroughly inspect connector P2. Thoroughly

inspect the connectors at the valve cover base.

Refer to Troubleshooting, “Electrical Connectors -

Inspect” for details.

Perform a 45 N (10 lb) pull test on each of the

wires in the ECM connector that are associated

with injector solenoids.

Check the screw for the ECM connector for the

correct torque of 5.0 N·m (44 lb in).

Check the harness and wiring for abrasion and for

pinch points from the injectors to the ECM.

Expected Result:

All connectors, pins, and sockets are completely

coupled and/or inserted and the harness is free of

corrosion, of abrasion and of pinch points.

Results:

•

OK – The harness is OK. Proceed to Test Step 2.

•

Not OK – There is a fault in the connectors and/or

the harness.

Repair:

Repair the connectors or the harness or

replace the connectors or the harness. Ensure that

all of the seals are correctly installed and ensure

that the connectors are completely coupled.

Use the electronic service tool in order to clear all

logged diagnostic codes and then verify that the

repair eliminates the fault.

STOP.
