M6 Brass NPT Screw Threaded Car In-car Temperature Sensor 5k Ohm 3950

Working principle Of The In-car Temperature Sensor

The higher the interior temperature indicated by the interior temperature sensor, the more the hybrid door moves toward the colder direction, and the lower the temperature of the air outlet. Anyway, the lower the interior temperature indicated by the interior temperature sensor, the hotter the hybrid door becomes. Moving in the direction, the higher the temperature of the air outlet. The temperature sensor in the car is generally installed at the lower end of the dashboard. It is a thermistor with a negative temperature coefficient. The resistance of the thermistor will gradually decrease as the temperature rises. Its function is to detect whether the temperature in the car reaches the set value to control the work of the air-conditioning system.

Specification Of The In-car Temperature Sensor

Dimension Of The In-car Temperature Sensor (mm)

Method of detecting temperature sensor in car

(1) Voltage measurement
Remove the air conditioner controller, but the connector is not disconnected, turn the ignition switch to the "ON" position, use a multimeter to measure the voltage between the controller connection terminals TR and SG-3 (Figure 5-17), the measured voltage value Should decrease with the increase of temperature, the voltage should be 1.8～2.2V at 25℃, and 1.2～1.6V at 40℃.

(2) Resistance measurement
Remove the temperature sensor in the car and measure the resistance between terminal 1 and terminal 2 of the connector. The resistance should decrease with the increase of temperature. At 25℃, the resistance should be 1.65～1.75kΩ, and at 40℃, the resistance should be 0.55～0.65kΩ. If it is not normal, replace the temperature sensor in the car.
The in-car temperature sensor is also called the indoor temperature sensor. It is one of the important sensors of automatic air conditioning. It will affect the temperature of the air at the outlet, the speed of the blower, the position of the intake door, and the position of the mode door. It is usually installed in the suction device behind the dashboard.
