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?
All
Yes → NOTE: Before continuing, check the PCM harness connector
terminals for corrosion, damage, or terminal push out. Repair as
necessary. Replace and program the Powertrain Contorl Module
in accordance with the Service Information.
