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 powertrain control module (PCM) energizes the solenoid.

Conditions for Running the DTC

The PCM requested the engine shut-off (ESO) solenoid ON (test 1).

or

The PCM requested the engine shut-off (ESO) solenoid OFF (test 2).

Conditions for Setting the DTC
    • The control circuit voltage at the PCM is less than 8 volts (test 1).
    • The conditions are met for 2 seconds.

or

    • The control circuit voltage at the PCM is greater than 8 volts (test 2).
    • The conditions are 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 is stored in the Failure Records.

Conditions for Clearing the MIL/DTC
    • The PCM will turn the MIL off after 3 consecutive trips without a fault condition.
    • A history DTC clears after 40 consecutive warm-up cycles, if this or any other emission related diagnostic does not report any failures.
    • The scan tool Clear Info function was used.

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.

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

    2.

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