Front Evaporator Temperature Sensor: Inspection
- INSPECT EVAPORATOR TEMPERATURE SENSOR
- Disconnect the connector from the evaporator temperature sensor.
- Measure the resistance according to the value(s) in the table below.
Standard resistance
TESTER CONNECTION SPECIFIED CONDITION CHARTTester Connection Condition Specified Condition E48-1 - E48-2 -10°C (14°F) 7.30 to 9.10 kΩ -5°C (23°F) 5.65 to 6.95 kΩ 0°C (32°F) 4.40 to 5.35 kΩ 5°C (41°F) 3.40 to 4.15 kΩ 10°C (50°F) 2.70 to 3.25 kΩ 15°C (59°F) 2.14 to 2.58 kΩ 20°C (68°F) 1.71 to 2.05 kΩ 25°C (77°F) 1.38 to 1.64 kΩ 30°C (86°F) 1.11 to 1.32 kΩ NOTE:- Hold the sensor only by its connector. Touching the may change the resistance value.
- When measuring, the sensor temperature must be the same as the ambient temperature.
HINT:
As the temperature increases, the resistance decreases (see Fig 1).
If the resistance is not as specified, replace the evaporator temperature sensor.
