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 PCM energizes the solenoid.

Conditions for Running the DTC

The PCM requested ESO ON.

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.

•	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 fails. 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 during which the diagnostic does not fail (coolant temperature has risen 5°C (40°F) from the start up coolant temperature and the engine coolant temperature exceeds 71°C (160°F) that same ignition cycle).

•	Use of a scan tool will clear the DTC.

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.

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

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

Step

Action

Value(s)

Yes

Important: Before clearing any DTCs, use the scan tool to save Freeze Frame and the Failure records for reference. The control module's data is deleted once the Clear Info function is used.

Was the Powertrain On-Board Diagnostic (OBD) System Check performed?

Go to Step 2

Go to Powertrain On Board Diagnostic (OBD) System Check

Turn the ignition OFF.
Disconnect the ESO harness electrical connector.
Turn ON the ignition, leaving the engine OFF.
With a J 35616-200 , unpowered test lamp connected to chassis ground, probe the ESO ignition feed circuit at the engine harness connector.

Is the test lamp ON?

Go to Step 3

Go to Step 6

Turn the ignition OFF.
With a J 35616-200 , unpowered test lamp, jumper the ESO engine harness terminals together.
Turn the ignition ON leaving the engine OFF.

Is the test lamp ON?

Go to Step 4

Go to Step 7

Turn the ignition ON leaving the engine OFF.
With a J 35616-200 , unpowered test lamp, connected to B+, probe the ESO control circuit.
With the scan tool, command the ESO solenoid ON and OFF.

Does the test lamp turn ON and OFF with each command?

Go to Step 5

Go to Step 8

Check the ESO harness for a proper connection, and replace the terminals if necessary. Refer to Wiring Repairs in Wiring Systems.

Did you perform a repair?

Go to Step 13

Go to Step 11

Check the ESO ignition feed circuit for the following:

•	An open wire

•	An open fuse

Repair the problem as necessary. Refer to Wiring Repairs in Wiring Systems.

Is the action complete?

Go to Step 13

Turn the ignition ON leaving the engine OFF.
With a J 35616-200 , unpowered test lamp connected to ground, probe the ESO control circuit at the ESO harness connector.

Is the test lamp ON?

Go to Step 10

Go to Step 9

Repair the short to ground on the ESO control circuit. Refer to Wiring Repairs in Wiring Systems.

Is the action complete?

Go to Step 13

Check the ESO control circuit for the following conditions:

•	An open wire

•	Proper connection at the PCM

If a problem is found, repair it as necessary. Refer to Wiring Repairs in Wiring Systems.

Is the action complete?

Go to Step 13

Go to Step 12

Check the ESO control circuit for a short to voltage.
If a problem is found, repair it as necessary. Refer to Wiring Repairs in Wiring Systems.

Is the action complete?

Go to Step 13

Go to Step 12

Important: The new injection pump must be timed. Refer to Fuel Injection Pump Timing Adjustment .

Replace the injection pump. Refer to Fuel Injection Pump Replacement .

Is the action complete?

Go to Step 13

Important: The new PCM must be programmed. Refer to Powertrain Control Module Replacement/Programming .

Replace the PCM.

Is the action complete?

Go to Step 13

Using the scan tool, clear the DTCs.
Start the engine.
Allow the enigne to idle until the normal operating temperature is reached.
Select the DTC and the Specific DTC functions.
Enter the DTC that was set.
Operate the vehicle within the conditions for setting this DTC until the scan tool indicates the diagnostic Ran.

Does the scan tool indicate the diagnostic Passed?

Go to Step 14

Go to Step 2

Does the scan tool display any additional undiagnosed DTCs?
