P0215

CIRCUIT DESCRIPTION
The injection pump fuel supply line has a solenoid controlled shut-off 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 Powertrain Control Module (PCM) energizes the solenoid.

CONDITIONS FOR RUNNING THE DTC
The ignition in the ON position or the engine is operating.

CONDITIONS FOR SETTING THE DTC
^ The PCM has requested the Engine Shut-down (ESO) solenoid ON and the control circuit voltage at the PCM is more than 8 volts.
^ All of the diagnostic set conditions are met for 2 seconds.

or

^ The PCM has requested the ESO OFF and the control circuit voltage at the PCM is less than 8 volts.
^ All of the diagnostic set conditions are met for 2 seconds.

ACTION TAKEN WHEN THE DTC SETS
^ The control module stores the DTC information into memory when the diagnostic runs and fails.
^ The Malfunction Indicator Lamp (MIL) will not illuminate.
^ The control module records the operating conditions at the time the diagnostic fails. The control module stores this information in the Failure Records.
^ The driver information center, if equipped, may display a message.

CONDITIONS FOR CLEARING THE DTC
^ A current DTC "Last Test Failed" clears when the diagnostic runs and passes.
^ A history DTC clears after 40 consecutive warm-up cycles, if no failures are reported by this or any other non-emission related diagnostic.
^ Use a scan tool in order to clear the DTC.

CONDITIONS FOR CLEARING THE MIL/DTC
^ A History DTC clears after forty consecutive warm-up cycles, if this or any other emission related diagnostic does not report any failures
^ The use of a scan tool.

DIAGNOSTIC AIDS
An open in the control circuit or the ignition feed circuit will cause a DTC P0215. Also a no start condition will exist. The scan tool has the ability to turn the engine shut-off solenoid ON and OFF. This can be used as a quick operational check.

An intermittent may be caused by any of the following conditions:
^ A poor connection Rubbed through wire insulation
^ A broken wire inside the insulation

Thoroughly check any circuitry that is suspected of causing the intermittent complaint. Refer to Testing for Electrical Intermittents in Diagrams.

If a repair is necessary, then refer to Wiring Repairs or Connector Repairs in Diagrams.

TEST DESCRIPTION

Steps 1-3:

Steps 4-14:

The numbers below refer to the step numbers 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.
