2. Check for a Failed Sensor
A. Connect to the electronic service tool.
B. Turn the keyswitch to the ON position.
C. Disconnect a sensor on the suspect sensor supply circuit.
D. Monitor the electronic service tool when the sensor is discon-
nected to see if the active code changes to logged.
E. Connect the suspect sensor to the wiring harness
F. Repeat steps C through E for each sensor on the suspect sensor
supply.
Failed
Sensor
Result: The suspect sensor supply active code changes to
logged when a sensor is unplugged.
Repair: Replace the failed sensor.
Verify that the repair resolved the problem.
Result: The suspect sensor supply active code remains ac-
tive after all sensors on the sensor supply circuit have been
checked.
Repair: A failed wiring harness has been detected. Repair
or replace the wiring harness.
Verify that the repair resolved the problem.
