What is the channel number of the Volkswagen outdoor temperature sensor?
1 Answers
The channel numbers for the Volkswagen outdoor temperature sensor are 001 and 003. Here is an introduction to the automotive outdoor temperature sensor: 1. Overview of the automotive outdoor temperature sensor: The outdoor temperature sensor detects the ambient temperature and transmits the detected temperature to the engine's ECU, converting it into an electrical signal. It determines the temperature setting of the automatic air conditioning system without manual intervention, adjusting the air conditioning to the most suitable temperature. 2. The outdoor temperature sensor is also known as the ambient temperature sensor: It is usually installed near the front bumper or grille. Its sensing element uses a negative temperature coefficient thermistor. The detection method for the outdoor temperature sensor is the same as that for the coolant temperature sensor. You can measure its resistance using the ohmmeter function of a multimeter. The resistance at room temperature should be between 1.6 and 1.8 KΩ, with higher resistance at lower temperatures. If the resistance exceeds the specified value, it indicates an open circuit in the sensor wiring or poor contact at the connector, which can affect the normal operation of the vehicle's air conditioning system. Further inspection or replacement may be necessary.
