P0215

DTC P0215 Engine Shutoff Control Circuit






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 opened and the fuel is supplied to the injection pump. By providing a ground path, the PGM energizes the solenoid.

Conditions for Running the DTC

The PCM requested ESO ON.

or

The PCM requested the ESO OFF.

Conditions for Setting the DTC

^ The control circuit voltage at the PCM is greater than 8 volts.
^ All diagnostic set conditions met for 2 seconds.
or
^ The control circuit voltage at the PCM is less than 8 volts.
^ All 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 tails. This information is stored in the Failure Records.

Conditions for Clearing the MIL/DTC

^ A History DTC will clear after forty consecutive warm-up cycles, if this or any other emission related diagnostic does not report any failures.
^ Use of a scan tool will clear the DTC.

Diagnostic Aids

An open in the control circuit or the ignition teed 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.
