AMBIENT TEMPERATURE SENSOR - INSPECTION
| 1. INSPECT AMBIENT TEMPERATURE SENSOR |
Measure the resistance according to the value(s) in the table below.
- Standard Resistance:
Tester Connection Condition Specified Condition 1 - 2 10°C (50°F) 3.00 to 3.73 kΩ 15°C (59°F) 2.45 to 2.88 kΩ 20°C (68°F) 1.95 to 2.30 kΩ 25°C (77°F) 1.60 to 1.80 kΩ 30°C (86°F) 1.28 to 1.47 kΩ 35°C (95°F) 1.00 to 1.22 kΩ 40°C (104°F) 0.80 to 1.00 kΩ 45°C (113°F) 0.65 to 0.85 kΩ 50°C (122°F) 0.50 to 0.70 kΩ 55°C (131°F) 0.44 to 0.60 kΩ 60°C (140°F) 0.36 to 0.50 kΩ
If the result is not as specified, replace the ambient temperature sensor.
- 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).
