The Engine Control Module (ECM) detects one of the following items after attempting to operate the injector:

A low current condition (open circuit) exists in the wiring for the cylinder injector solenoid.
A high current condition (short circuit) exists in the injector solenoid.

Probable Causes:

1) ECM Connection/Harness
2) Cylinder injector failure
3) Injector solenoid failure
4) Harness from ECM to valve cover connector
5) ECM failure
6) Injector harness under valve cover
