Car water temperature sensor failure phenomenon, the performance of the water temperature sensor broken

The water temperature sensor we are talking about today is a device that converts the temperature of the cooling water into an electrical signal to adjust the corresponding control unit.Yuan. Although this sensor looks relatively small and exquisite, if there is a malfunction, the consequences cannot be underestimated. So, what are the malfunctions of the car water temperature sensor? Today we will talk about the performance of the water temperature sensor broken.

Water temperature gauge on the dashboard

The most obvious failure phenomenon is that the indicator needle of the water temperature meter does not move, and secondly, it will always point to the highest position.So when weFindWhen this phenomenon occurs, it is probably because the water temperature sensor is malfunctioning and needs to be repaired and replaced in time.

Cold start/Idle speed is unstable

When the water temperature sensor fails, the ECU naturally cannot get the signal of the over-rich mixture. At this time, it can only provide the engine's thinner mixture. Especially when the car is in a cold state, it may be more difficult to start the engine. Even if it catches fire to you, the engine's power and stability are still lacking, and it may suddenly turn off during idling or driving.

Car's fuel consumption

It is necessary to know that the ECU needs to correct the fuel injection volume and ignition advance angle of the car in time according to the electrical signal provided by the water temperature sensor. So once the water temperature sensor fails, it will naturally affect the control unit, which will cause the car's fuel consumption to increase.
