Troubleshooting Test Steps Values Results
1. Check For Active Diagnostic Codes
A. Turn the keyswitch to the OFF position.
B. Connect the electronic service tool to the diagnostic connector.
C. Turn the keyswitch to the ON position. Download the "Product Summary Report" from the engine ECM before performing any troubleshooting or clearing diagnostic trouble codes.
D. Use the electronic service tool to check that coolant temperature, intake manifold air temperature, and NRS temperature are all at least 5° C (41° F).
Note: Wait at least 10 seconds in order for the diagnostic codes to become active.
E. Use the electronic service tool to monitor active diagnostic codes or recently logged diagnostic codes. Look for an active or logged -3 or -4 codes for the pressure sensor or the barometric pressure sensor.
F. Use the electronic service tool to monitor active diagnostic codes or recently logged diagnostic codes. Look for an active or logged -13 code for a pressure sensor or the barometric pressure sensor.
G. Turn the keyswitch to the OFF position.
Diagnostic codes
Result: There are no active diagnostic codes for the pressure sensors.
If there are logged diagnostic codes for the intake manifold pressure sensor, the fault may be intermittent.
Repair: Refer to Troubleshooting, "Electrical Connectors - Inspect" to identify intermittent faults.
Result: One or more of the temperature sensors is reading less than 5° C (41° F).
Proceed to Test Step 4.
Result: There is an active -3 or -4 diagnostic code for a pressure sensor or the barometric pressure sensor.
Repair: Troubleshoot these codes before continuing with this procedure.
Result:Several -13 diagnostic codes are active.
Proceed to Test Step 5.
Result: There is an active 3358-13 (3385-13), 3563-13 (1785-13), 3609-13 (3464-13), or 3837-13 (3493-13) diagnostic code for only one sensor.
Proceed to Test Step 6.
There is an active 411-13 (3387-13) diagnostic code.
Proceed to Test Step 2.
2. Check the Signal Wire for a Short Circuit
A. Turn the keyswitch to the OFF position.
B. Disconnect the P2 connector and disconnect the connector from the suspect sensor.
C. Check the resistance between the applicable signal terminal on the P2 connector and all other terminals on the P2 connector.
Greater than 100 Ohms
Result: At least one of the resistance measurements is less than 100 Ohms. The fault is in the engine harness.
Repair: Repair the faulty connector or replace the faulty harness. Use the electronic service tool to verify that the repair eliminates the fault.
Result: All resistance measurements are greater than 100 Ohms.
Proceed to Test Step 3.
3. Create a Short Circuit at the Sensor Connector
A. Turn the keyswitch to the OFF position.
B. Disconnect the connector for the suspect sensor.
C. Fabricate a jumper wire that is 150 mm (6 inch) long. Crimp a terminal to both ends of the wire.
D. Use the jumper to connect the sensor signal terminal to the sensor ground terminal on the harness connector for the suspect sensor.
E. Turn the keyswitch to the ON position. Do not start the engine.
F. Access the "Active Diagnostic Codes" screen on the electronic service tool and check for an active XXXX-4 diagnostic code for the suspect sensor.
G. Remove the jumper. Reconnect the sensor.
