INSPECTION PROCEDURE
1. INSPECT COOLER (ROOM TEMPERATURE. SENSOR) THERMISTOR
(a) Check the resistance.
(1) Measure the resistance according to the value(s) in the table below. Text in Illustration
*a |
Component without harness connected
(cooler thermistor (room temperature sensor)) |
*b |
Sensing Portion |
*c |
Resistance (kΩ) |
*d |
Temperature (°C (°F)) |
Standard Resistance:
Tester Connection | Switch Condition | Specified Condition |
1 - 2 |
10 °C |
3.00 to 3.73 kΩ |
15 °C |
2.45 to 2.88 kΩ |
20 °C |
1.95 to 2.30 kΩ |
25 °C |
1.60 to 1.80 kΩ |
30 °C |
1.28 to 1.47 kΩ |
35 °C |
1.00 to 1.22 kΩ |
40 °C |
0.80 to 1.00 kΩ |
45 °C |
0.65 to 0.85 kΩ |
50 °C |
0.50 to 0.70 kΩ |
55 °C |
0.44 to 0.60 kΩ |
60 °C |
0.36 to 0.50 kΩ |
NOTICE:
- 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.
If the result is not as specified, replace the cooler thermistor (room temperature sensor). |
