Circuit Description
The injection pump fuel supply line has a solenoid controlled shutoff which is located in the injection pump. When the solenoid is energized (key in the run position), the valve is open and the fuel is supplied to the injection pump. By providing a ground path, the PCM energizes the solenoid. This is a type D DTC.

Conditions for Setting the DTC

^ The PCM requested Engine Shut-off (ESO) ON.
^ The control circuit voltage at the PCM is greater than 8 volts.
^ The conditions met for 2 seconds.

OR

^ The PCM requested the ESO OFF.
^ The control circuit voltage at the PCM is less than 8 volts.
^ The conditions met for 2 seconds.

Action Taken When the DTC Sets
P0215 will not turn ON the Malfunction Indicator Lamp (MIL).

Conditions for Clearing the MIL/DTC
A History DTC will clear after forty consecutive warm-up cycles during which the diagnostic does not fail (coolant temperature has risen 5°C (40°F) from the start up coolant temperature and the engine coolant temperature exceeds 71°C (180°F) of that same ignition cycle).

^ Use of a Scan tool will clear the DTC.

Diagnostic Aids
An open in the control circuit or the ignition feed circuit will cause a P0215. Also a no start condition will exist. The Scan Tool has the ability to turn the engine shutoff solenoid ON and OFF. This can be used as a quick operational check.

Test Description
The number(s) below refer to the Step number(s) on the Diagnostic Table.

3. This Step will check the control circuit for an open.
