Where is the car temperature sensor located?

The water temperature sensor is generally installed on the water passage or radiator of the car. Relevant information is as follows: Introduction: The car water temperature sensor is installed on the water jacket of the engine cylinder block or cylinder head, in direct contact with the coolant, and can be used to measure the temperature of the engine coolant. Strictly speaking, water temperature sensors are divided into two major categories. Regardless of the type, their internal structure consists of a thermistor with a resistance ranging from 275 ohms to 6500 ohms. Moreover, the lower the temperature, the higher the resistance; the higher the temperature, the lower the resistance. Principle of the car water temperature sensor: The interior of the car water temperature sensor is a thermistor. The lower the temperature, the higher the resistance; conversely, the higher the temperature, the lower the resistance. It is installed on the water jacket of the engine cylinder block or cylinder head, in direct contact with the cooling water, thereby measuring the temperature of the engine coolant. The electronic control unit measures the temperature of the engine coolant based on this change. The lower the temperature, the higher the resistance; conversely, the higher the temperature, the lower 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 current operating state of the car, whether it is stopped or moving, or how long it has been running.
