AMBIENT TEMPERATURE SENSOR CIRCUIT (CONTINUED)
3.
READ AMBIENT TEMPERATURE SENSOR VOLTAGE WITH DRB III
Turn the ignition off.
Connect a jumper wire between the Ambient Temperature Sensor Sig-
nal circuit and the Sensor Ground circuit.
Turn the ignition on.
With the DRB III , read the Ambient Temperature Sensor voltage.
Does the DRB III
greater?
Yes >> Go to 4
No >> Replace the Ambient Temperature Sensor. (Refer to 24 -
HEATING & AIR CONDITIONING/CONTROLS/AMBIENT
TEMP SENSOR - REMOVAL)
Perform BODY VERIFICATION TEST.
4.
MEASURE THE RESISTANCE OF THE AMBIENT TEMPERATURE SENSOR SIGNAL CIRCUIT
Turn the ignition off.
Disconnect the Instrument Cluster C1 harness connector.
Note: Check connector - Clean/repair as necessary.
Measure the resistance of the Ambient Temperature Sensor Signal cir-
cuit from the Instrument Cluster harness connector to the Ambient
Temperature Sensor harness connector.
Is the resistance below 5.0 ohms?
Yes >> Go to 5
No >> Repair the Ambient Temperature Sensor Signal circuit for
an open.
Perform BODY VERIFICATION TEST.
