5.
MEASURE THE RESISTANCE OF THE SENSOR GROUND CIRCUIT
With the ignition off.
Measure the resistance of the Sensor Ground circuit from the Power-
train Control Module harness connector to the Engine Coolant Temper-
ature Sensor harness connector.
Is the resistance below 5.0 ohms?
Yes >> Replace the Powertrain Control Module. (Refer to 8 -
ELECTRICAL/ELECTRONIC CONTROL MODULES/POW-
ERTRAIN CONTROL MODULE - REMOVAL).
Perform BODY VERIFICATION TEST.
No >> Repair the Sensor Ground circuit for an open.
Perform BODY VERIFICATION TEST.
6.
READ ENGINE COOLANT TEMPERATURE SENSOR VOLTAGE WITH DRB III
Turn the ignition off.
Disconnect the Engine Coolant Temperature Sensor harness connec-
tor.
Note: Check connector - Clean/repair as necessary.
Turn the ignition on.
With the DRB III , read the Engine Coolant Temperature Sensor volt-
age.
Does the DRB III display ENGINE COOLANT TEMP: 4.5 VOLTS
or greater?
Yes >> Go to 7
No >> Go to 9
