Circuit Description

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

Conditions for Setting the DTC

^ The PCM requested the ESO ON.

^ The control circuit voltage at the PCM is greater than 8 volts.

^ All of the diagnostic set conditions met for 2 seconds.

or

^ The PCM requested the ESO OFF.

^ The control circuit voltage at the PCM is less than 8 volts.

^ All of the diagnostic set conditions met for 2 seconds.

Action Taken When the DTC Sets

^ The PCM will not illuminate the Malfunction Indicator Lamp (MIL).

^ The PCM records the operating conditions at the time the diagnostic fails. This information will store in the Failure Records.

Conditions for Clearing the MIL/DTC

^ A History DTC will clear when forty consecutive warm-up cycles that the diagnostic does not fail (coolant temperature has risen 5°C (40°F) from start up coolant temperature and engine coolant temperature exceeds 71°C (160°F)) that same ignition cycle.

^ Use of a Scan tool

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

Number(s) below refer to the step number(s) on the Diagnostic Table.

3. This step will check the ESO control circuit for an open.

10. After repairing the circuit for a short to voltage, check the solenoid for proper operation.
