6 Turn the ignition off.
Disconnect the IAT 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 (K4) Sensor ground circuit from the IAT 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 (K4) Sensor ground circuit.
No
7 Turn the ignition off.
Disconnect the IAT Sensor harness connector.
Disconnect the PCM harness connector.
Measure the resistance between ground and the (K21) IAT Signal circuit in the IAT
Sensor harness connector.
Is the resistance below 100 ohms?
Yes → Repair the short to ground in the (K21) IAT Signal circuit.
→ Go To 8
No
8 Turn the ignition off.
Disconnect the IAT Sensor harness connector.
Disconnect the PCM harness connector.
Measure the resistance between the (K4) Sensor ground circuit and the (K21) IAT
Sensor Signal circuit at the IAT Sensor harness connector.
Is the resistance below 5.0 ohms?
Yes → Repair the (K4) Sensor ground circuit shorted to the (K21) IAT
→ NOTE: Before continuing, check the PCM harness connector
No
