TEST
6 NOTE: Visually inspect both the component and the PCM connectors. Look
for damage, partially broken wires and backed out or corroded terminals
Turn the ignition off.
Disconnect the applicable Temperature Sensor harness connector.
Ignition on, engine not running.
Measure the voltage of the Signal circuit in the applicable Temperature Sensor
harness connector.
Is the voltage above 5.2 volts?
Yes → Repair the short to battery voltage in the Signal circuit.
→ Go To 7
No
7 Turn the ignition off.
Disconnect the applicable Temperature Sensor harness connector.
Ignition on, engine not running.
With the DRBIII , read the Temperature Sensor voltage.
Is the voltage above 4.6 volts?
Yes → Go To 8
→ Go To 11
No
8 Turn the ignition off.
Disconnect the applicable Temperature Sensor harness connector.
Using a jumper wire, jumper across the Temperature Sensor harness connector.
Ignition on, engine not running.
With the DRBIII , read the Temperature voltage.
Is the voltage below 1.0 volt?
Yes → Replace the applicable Temperature Sensor.
→ Go To 9
No
9 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 Signal circuit from the Temperature 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 Signal circuit.
No
