Toyota Corolla Cross: Inspection
INSPECTION
PROCEDURE
1. INSPECT NO. 1 COOLER THERMISTOR
(a) Check the resistance.
(1) Measure the resistance according to the value(s) in the table below.
|
*a | Component without harness connected (No. 1 Cooler Thermistor) |
*b | Sensing Portion |
|
*c | Resistance (kΩ) |
*d | Temperature (°C (°F)) |
|
*e | Allowable Range |
- | - |
Standard Resistance:
|
Tester Connection | Condition |
Specified Condition |
|---|---|---|
|
1 - 2 | -10°C (14°F) |
7.30 to 9.10 kΩ |
| 1 - 2 |
-5°C (23°F) | 5.65 to 6.95 kΩ |
|
1 - 2 | 0°C (32°F) |
4.40 to 5.35 kΩ |
| 1 - 2 |
5°C (41°F) | 3.40 to 4.15 kΩ |
|
1 - 2 | 10°C (50°F) |
2.70 to 3.25 kΩ |
| 1 - 2 |
15°C (59°F) | 2.14 to 2.58 kΩ |
|
1 - 2 | 20°C (68°F) |
1.71 to 2.05 kΩ |
| 1 - 2 |
25°C (77°F) | 1.38 to 1.64 kΩ |
|
1 - 2 | 30°C (86°F) |
1.11 to 1.32 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.
HINT:
As the temperature increases, the resistance decreases (see the graph).
If the resistance is not as specified, replace the No. 1 cooler thermistor.
