ENGINE COOLANT TEMPERATURE SENSOR CIRCUIT (CONTINUED)
3.
READ ENGINE COOLANT TEMPERATURE SENSOR VOLTAGE WITH DRB III
Turn the ignition off.
Connect a jumper wire between the Engine Coolant Temperature Sen-
sor Signal circuit and the Sensor Ground circuit.
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 4
No >> Replace the Engine Coolant Temperature Sensor. (Refer
to 7 - COOLING/ENGINE/ENGINE COOLANT TEMP
SENSOR - REMOVAL).
Perform BODY VERIFICATION TEST.
4.
MEASURE THE RESISTANCE OF THE ENGINE COOLANT TEMPERATURE SENSOR SIGNAL CIRCUIT
Turn the ignition off.
Disconnect the Powertrain Control Module harness connector.
Note: Check connector - Clean/repair as necessary.
Measure the resistance of the Engine Coolant Temperature Sensor
Signal circuit from the Powertrain Control Module harness connector to
the Engine Coolant Temperature Sensor harness connector.
Is the resistance below 5.0 ohms?
Yes >> Go to 5
No >> Repair the Engine Coolant Temperature Sensor Signal cir-
cuit for an open.
Perform BODY VERIFICATION TEST.
