2 Turn the ignition off.
Disconnect the ECT Sensor harness connector.
NOTE: Visually inspect both the component and the PCM connectors. Look
for damaged, partially broken wires, and backed out or corroded terminals.
Ignition on, engine not running.
Measure the voltage on the (K2) ECT Signal circuit in the ECT Sensor harness
connector.
Is the voltage above 5.2 volts?
All
Yes → Repair the short to battery voltage in the (K2) ECT Signal circuit.
Perform POWERTRAIN VERIFICATION TEST VER-5-NGC.
No → Go To 3
3 Turn the ignition off.
Disconnect the ECT Sensor harness connector.
Ignition on, engine not running.
With the DRBIIIt, read the ECT Sensor voltage.
Is the voltage above 4.9 volts?
All
Yes → Go To 4
No → Go To 7
4 Turn the ignition off.
Disconnect the ECT Sensor harness connector.
Using a jumper wire, jumper across the ECT Sensor harness connector.
Ignition on, engine not running.
With the DRBIIIt, read the ECT Sensor voltage.
Is the voltage below 0.1 volt?
All
Yes → Replace the ECT Sensor.
Perform POWERTRAIN VERIFICATION TEST VER-5-NGC.
No → Go To 5
5 Turn the ignition off.
Disconnect the ECT 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 (K2) ECT Signal circuit from the ECT Sensor harness
connector to the appropriate terminal of special tool #8815.
Is the resistance below 5.0 ohms?
All
Yes → Go To 6
No → Repair the open in the (K2) ECT Signal circuit.
Perform POWERTRAIN VERIFICATION TEST VER-5-NGC.
