Toyota Yaris: Front Evaporator Temperature Sensor / 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 |
h5-1 - h5-2 | -10°C (14°F) | 7.30 to 9.10 kΩ |
h5-1 - h5-2 | -5°C (23°F) | 5.65 to 6.95 kΩ |
h5-1 - h5-2 | 0°C (32°F) | 4.40 to 5.35 kΩ |
h5-1 - h5-2 | 5°C (41°F) | 3.40 to 4.15 kΩ |
h5-1 - h5-2 | 10°C (50°F) | 2.70 to 3.25 kΩ |
h5-1 - h5-2 | 15°C (59°F) | 2.14 to 2.58 kΩ |
h5-1 - h5-2 | 20°C (68°F) | 1.71 to 2.05 kΩ |
h5-1 - h5-2 | 25°C (77°F) | 1.38 to 1.64 kΩ |
h5-1 - h5-2 | 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.
If the specified condition is not met, replace the No. 1 cooler thermistor.
