TEST
8 Turn the ignition off.
Disconnect the MAP Sensor harness connector.
Disconnect the PCM harness connector.
Measure the resistance between ground and the 5 Volt Supply circuit in the MAP
Sensor harness connector.
Is the resistance below 100 ohms?
Yes → Repair the short to ground in the 5 Volt Supply circuit.
→ Go To 9
No
9 Turn the ignition off.
Disconnect the MAP 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 5 Volt Supply circuit from the MAP Sensor harness
connector to the appropriate terminal of special tool #8815.
Is the resistance below 5.0 ohms?
Yes → Go To 10
→ Repair the open in the 5 Volt Supply circuit.
No
10 NOTE: Before continuing, check the PCM harness connector terminals for
corrosion, damage, or terminal push out. Repair as necessary.
If there are no possible causes remaining, view repair.
