Turn the ignition off.
Disconnect the applicable Temperature Sensor harness connector.
Disconnect the PCM harness connector.
CAUTION: DO NOT PROBE THE PCM HARNESS CONNECTORS. PROBING
THE PCM HARNESS CONNECTORS WILL DAMAGE THE PCM TERMI-
NALS RESULTING IN POOR TERMINAL TO PIN CONNECTION. INSTALL
MILLER SPECIAL TOOL #8815 TO PERFORM DIAGNOSIS.
Measure the resistance of the Sensor ground circuit from the Ambient Air Temper-
ature Sensor harness connector to the appropriate terminal of special tool #8815.
Is the resistance below 5.0 ohms?
Yes → NOTE: Before continuing, check the PCM harness connector
→ Repair the open in the Sensor ground circuit.
No
11
Turn the ignition off.
Disconnect the applicable Temperature Sensor harness connector.
Disconnect the PCM harness connector.
Measure the resistance between ground and the Signal circuit in the Temperature
harness connector.
Is the resistance below 100 ohms?
Yes → Repair the short to ground in the Signal circuit.
→ Go To 12
No
12
Turn the ignition off.
Disconnect the applicable Temperature Sensor harness connector.
Disconnect the PCM harness connector.
Measure the resistance between the Signal circuit and the Sensor ground circuit in
the Temperature Sensor harness connector.
Is the resistance below 100 ohms?
Yes → Repair the Sensor ground shorted to the Signal circuit.
→ NOTE: Before continuing, check the PCM harness connector
No
