P0215

CIRCUIT DESCRIPTION
The injection pump fuel supply line has a solenoid controlled shut-off which is located in the injection pump. When the solenoid is energized with the 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 more than 8 volts-Test 2.
^ The 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.

DIAGNOSTIC AIDS
An open in the control circuit or the ignition feed circuit will cause a DTC P0215. A no start condition will also 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.

TEST DESCRIPTION

Steps 1-4:

Steps 5-14:

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.
