What does false high temperature on Wuling Sunshine water temperature gauge mean?

[MacJoanna]

False high temperature on the Wuling Sunshine water temperature gauge means the engine temperature is actually not high, but the water temperature gauge gives an alarm. This is generally caused by a faulty water temperature sensor. Below are relevant explanations: 1. Definition of water temperature sensor: Typically, the water temperature sensor is a negative temperature coefficient thermistor installed in the engine cylinder head water jacket, directly contacting the coolant to measure the engine coolant temperature. The water temperature sensor is also an electronic component in the car circuit. If it fails, there is basically no way to repair it, and it must be replaced. 2. Symptoms of water temperature sensor failure: The water temperature gauge needle does not move or points to the highest position. Difficulty starting a cold engine, because when the water temperature sensor fails, it still shows the temperature signal of a hot engine during a cold start. The ECU cannot receive the signal for a rich mixture, so it can only provide the engine with a lean mixture. Increased fuel consumption, unstable idle; difficulty accelerating, even when the throttle is fully pressed, the engine speed does not increase.
