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/Harness2) Cylinder injector failure3) Injector solenoid failure4) Harness from ECM to valve cover connector5) ECM failure6) Injector harness under valve cover

The ECM is not receiving a correct throttle signal

The throttle signal is less than 5% or more than 95%

The Engine Control Module (ECM) detects that the keyswitch was cycled at least three times within one second. This indicates that the battery circuit to the keyswitch has an intermittent condition or a low battery condition while the engine is running. Note: This code can be generated by rapidly cycling the keyswitch. Some control modules on the vehicle require this action in order to prompt flash codes. If this occurs, clear the logged diagnostic codes in order to prevent future confusion or an incorrect diagnosis. Note: This code can also be generated when there is an attempt to restart the...
