What is the normal value of the Wuling Hongguang water temperature gauge?
1 Answers
Wuling Hongguang water temperature gauge 90 degrees is normal. Extended information is as follows: 1. Introduction: The inside of the car water temperature sensor is the car water temperature sensor. The lower the temperature, the greater the resistance; conversely, the smaller the resistance. It is installed on the water jacket of the engine block or cylinder head and is in direct contact with the cooling water, thereby measuring the temperature of the engine cooling water. 2. Principle: The electronic control unit measures the temperature of the engine cooling water based on this change. The lower the temperature, the greater the resistance; conversely, the smaller the resistance. The electronic control unit measures the temperature of the engine cooling water based on this change, which serves as a correction signal for fuel injection and ignition timing. Simply put, the engine water temperature can be used to understand the operating state of the car, whether it is stopped or moving, or how long it has been moving, etc.
