Where is the Touareg Water Temperature Sensor 2 Located?

[VonAmara]

Touareg water temperature sensor 2 is located inside the bumper at the front of the engine, in direct contact with the coolant. Below is more information about the water temperature sensor: 1. Principle of the water temperature sensor: The electronic control unit measures the temperature of the engine coolant based on this change. The lower the temperature, the greater the resistance; conversely, the smaller the resistance. The electronic control unit uses this change to measure the temperature of the engine coolant as a correction signal for fuel injection and ignition timing. The temperature of the engine coolant can be used to understand the operating state of the car, whether it is stopped or moving, or how long it has been running. 2. Structure of the water temperature sensor: There is a wire connected to the electronic control unit (ECU). The car water temperature sensor is installed on the water jacket of the engine block or cylinder head, in direct contact with the coolant, to measure the temperature of the engine coolant. The temperature sensor used in the coolant temperature gauge is a negative temperature coefficient thermistor, whose resistance decreases as the temperature increases.
