Troubleshooting Test Steps
Values Results
3. Create a Short Circuit at the Harness Connector for the
Solenoid
A. Turn the keyswitch to the OFF position.
B. Disconnect the connector for the suspect solenoid.
C. Fabricate a jumper wire that is 150 mm (6 inch) long.
D. Install the wire between the two pins on the harness con-
nector for the suspect solenoid in order to create a short
circuit.
E. Turn the keyswitch to the ON position. Wait for 10 seconds.
Check for active diagnostic codes on the electronic service
tool.
F. Remove the jumper wire from the connector for the solenoid
valve.
Open circuit Result: An -5 diagnostic code was active before instal-
ling the jumper. An -6 diagnostic code is active when the
jumper is installed - There is a fault in the solenoid.
Repair: Temporarily connect a replacement for the sus-
pect valve to the harness.
Turn the keyswitch to the ON position. Use the electronic
service tool in order to check for active diagnostic codes.
Wait at least 30 seconds in order for the codes to be
displayed.
If the fault is eliminated, reconnect the suspect valve. If
the fault returns, permanently install the replacement
valve. Refer to Disassembly and Assembly for the cor-
rect procedure.
Result: A -5 diagnostic code is still active with the jump-
er installed.
Proceed to Test Step 4.
4. Check the Wiring for an Open Circuit
A. Turn the keyswitch to the OFF position.
B. Disconnect the P2 connector and the connector for the sus-
pect valve.
C. Use a multimeter to check the resistance between the sig-
nal terminal on P2 and the signal terminal on the valve
connector.
Refer to Illustration 147 .
D. Use a multimeter to check the resistance between the re-
turn terminal on P2 and the return terminal on the valve
connector.
Refer to Illustration 147 .
E. Reconnect the connectors.
Less than two Ohms Result: One of the measured resistances is greater than
two Ohms - There is a fault in the engine wiring harness
Repair: Repair the engine wiring harness or replace the
engine wiring harness.
Use the electronic service tool to clear all logged diag-
nostic codes and verify that the repair eliminates the
fault.
Result: All measured resistances are less than two
Ohms.
