for LHD


Remove the air duct temperature sensor LH ().

for RHD


Remove the air duct temperature sensor RH ().

Measure the resistance according to the value(s) in the table below.

  • Standard Resistance:
  • Tester ConnectionConditionSpecified Condition
    1 (+) - 2 (-)at 10°C (50°F)9.4 to 10.5 kΩ
    at 15°C (59°F)7.5 to 8.3 kΩ
    at 20°C (68°F)6.0 to 6.5 kΩ
    at 25°C (77°F)4.5 to 5.2 kΩ
    at 30°C (86°F)3.8 to 4.2 kΩ
    at 35°C (95°F)3.1 to 3.4 kΩ
    at 40°C (104°F)2.5 to 2.8 kΩ
    at 45°C (113°F)2.0 to 2.3 kΩ
    at 50°C (122°F)1.6 to 2.0 kΩ
    at 55°C (131°F)1.3 to 1.6 kΩ
    at 60°C (140°F)1.1 to 1.4 kΩ
  • NOTICE:
Touching the sensor even slightly may change the resistance value. Hold the connector of the sensor.
When measuring the resistance, the sensor temperature must be the same as the ambient temperature.
  • HINT:
  • As the temperature increases, the resistance decreases (see the graph).
  • If the resistance value is not as specified, replace the sensor.
