Test Step 1. Check For Active +5 Volt Sensor Supply Diagnostic Codes
Connect the electronic service tool to the diagnostic connector.
Turn the keyswitch to the ON position. Wait at least 15 seconds for activation of the diagnostic codes.
Verify that none of the following diagnostic codes are active:
262-03 5 Volt Sensor DC Power Supply voltage above normal
262-04 5 Volt Sensor DC Power Supply voltage below normalExpected Result:No 262 diagnostic codes are active.Results:
OK - Proceed to Test Step 2.
Not OK - A 262 diagnostic code is active.Repair: Perform the following diagnostic procedure: Troubleshooting, "5 Volt Engine Pressure Sensor Supply Circuit - Test".STOPTest Step 2. Verify All Active Diagnostic Codes
Turn the keyswitch to the ON position. Wait at least 15 seconds for activation of the diagnostic codes.
Verify if any of the following diagnostic codes are active:
100-03 Engine Oil Pressure Sensor voltage above normal
100-04 Engine Oil Pressure Sensor voltage below normal
100-10 Engine Oil Pressure Sensor abnormal rate of change
102-03 Boost Pressure Sensor voltage above normal
102-04 Boost Pressure Sensor voltage below normal
102-10 Boost Pressure Sensor abnormal rate of changeExpected Result:One or more of the diagnostic code is active.Results:
Yes - Proceed to Test Step 3.
No - Repair: If the preceding codes are logged, an intermittent condition may be causing the logged codes.Perform a "Wiggle Test" by using the electronic service tool in order to identify intermittent connections. Refer to Troubleshooting, "Electrical Connectors - Inspect".STOPTest Step 3. Inspect Electrical Connectors And Wiring

(24) Engine oil pressure
(26) +5V supply
(34) Sensor common
Thoroughly inspect the following terminal connections on the P1 ECM connector:
P1:14 Intake Manifold Pressure
P1:24 Engine Oil Pressure
P1:26 +5 V Supply
P1:34 Sensor Common
Thoroughly inspect the following engine pressure sensors:
J1/P1 ECM Engine Harness Connector
J20/P20 Machine Interface Connector
J200/P200 Intake Manifold Pressure Sensor
J201/P201 Engine Oil Pressure Sensor
Refer to Troubleshooting, "Electrical Connectors - Inspect".
Perform a 45 N (10 lb) pull test on each of the wires in the ECM connector and the sensor connectors that are associated with the active diagnostic code. Refer to Illustration 2.
Check the ECM connector (Allen head screw) for the correct torque of 6.0 N m (55 lb in).
Check the harness and wiring for abrasions and for pinch points from the sensors back to the ECM.
Perform a "Wiggle Test" by using the electronic service tool in order to identify intermittent connections. Refer to Troubleshooting, "Electrical Connectors - Inspect". Expected Result:All connectors, pins, and sockets should be completely coupled and inserted. The harness should be free of corrosion, abrasion, and pinch points.Results:
OK - Proceed to Test Step 4.
Not OK - Repair: Repair the connectors or the harness and/or replace the connectors or the harness. Ensure that all of the seals are correctly installed and ensure that the connectors are completely coupled.Verify that the repair eliminates the fault.STOPTest Step 4. Verify that the Diagnostic Code is Still Active
Turn the keyswitch to the ON position. Wait at least 15 seconds for activation of the diagnostic codes.
Use the electronic service tool to check for active diagnostic codes. Record all active diagnostic codes.
Determine if the fault is related to an open circuit diagnostic code or a short circuit diagnostic code. Expected Result:Either a short circuit diagnostic code is active or an open circuit diagnostic code is active.Results:
OK - Short circuit - A "voltage above normal" diagnostic code is active. Proceed to Test Step 5.
OK - Open circuit - A "voltage below normal" diagnostic code is active. Proceed to Test Step 6.
Not OK - A short circuit diagnostic code is not active. An open circuit diagnostic code is not active. An intermittent fault may exist.Repair: Perform a "Wiggle Test" by using the electronic service tool in order to identify intermittent connections. Refer to Troubleshooting, "Electrical Connectors - Inspect".STOPTest Step 5. Disconnect The Sensor In Order To Create An Open Circuit
Turn the keyswitch to the OFF position.
Disconnect the sensor connector of the sensor with the short circuit diagnostic code.
Turn the keyswitch to the ON position. Wait at least 15 seconds for activation of the diagnostic codes.
Use the electronic service tool to check the "Active Diagnostic Code" screen. Check for an open circuit diagnostic code. Expected Result:An "voltage above normal" diagnostic code for the disconnected sensor is now active.Results:
OK - A "voltage below normal" diagnostic code was active before disconnecting the sensor. An "voltage above normal" diagnostic code became active after disconnecting the sensor. Proceed to Test Step 7.
Not OK - There is a short circuit between the sensor harness connector and the ECM. Leave the sensor disconnected. Proceed to Test Step 9.Test Step 6. Measure the Sensor Supply Voltage
