EVAPORATOR TEMPERATURE SENSOR CIRCUIT (CONTINUED)
3.
READ EVAPORATOR TEMPERATURE SENSOR VOLTAGE WITH DRB III
Turn the ignition off.
Connect a jumper wire between the Evaporator Temperature Sensor
Signal circuit and the Sensor Ground circuit.
Turn the ignition on.
With the DRB III , read the Evaporator Temperature Sensor voltage.
Does the DRB III display EVAP TEMP: 4.5 VOLTS or greater?
Yes >> Go to 4
No >> Replace the Evaporator Temperature Sensor. (Refer to 24
- HEATING & AIR CONDITIONING/CONTROLS/EVAPO-
RATOR TEMPERATURE SENSOR - REMOVAL).
Perform BODY VERIFICATION TEST.
4.
MEASURE THE RESISTANCE OF THE EVAPORATOR TEMPERATURE SENSOR SIGNAL CIRCUIT
Turn the ignition off.
Disconnect the A/C Heater Control Module harness connector.
Note: Check connector - Clean/repair as necessary.
Measure the resistance of the Evaporator Temperature Sensor Signal
circuit from the A/C Heater Control Module harness connector to the
Evaporator Temperature Sensor harness connector.
Is the resistance below 5.0 ohms?
Yes >> Go to 5
No >> Repair the Evaporator Temperature Sensor Signal circuit
for an open.
Perform BODY VERIFICATION TEST.
