EVAPORATOR TEMPERATURE SENSOR SPECIFICATIONS
Scheme 1
Scheme 2
- In-car air temperature sensor is located at the lower crush pad.
- The sensor contains a thermistor which measures the temperature of the inside. The signal, decided by the resistance value which changes in accordance with perceived inside temperature, is delivered to heater control unit and according to this signal the control unit regulates in car temperature to intended value.
Scheme 3
- Ignition "OFF"
- Disconnect in-car temperature sensor.
- Using the multi-tester, Measure resistance between terminal "2" and "4" of in-car sensor.
