Toyota CH-R Service Manual: Inspection




(a) Check the resistance.

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


Component without harness connected

(No. 1 Cooler Thermistor)


Sensing Portion


Resistance (kΩ)


Temperature (°C (°F))


Allowable Range



Standard Resistance:

Tester Connection


Specified Condition

1 - 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

If the resistance is not as specified, replace the No. 1 cooler thermistor.


  • Hold the sensor only by its connector. Touching the sensing portion may change the resistance value.
  • When measuring, the sensor temperature must be the same as the ambient temperature.


As the temperature increases, the resistance decreases (see the graph).

If the specified condition is not met, replace the No. 1 cooler thermistor.
