failing temp reading on water gauge

• 2023-03-21

The possible causes of failing water temp reading on water gauge are: 1. The water temperature sensor is faulty. 2. Line fault. 3. The water temperature gauge on the vehicle dashboard is faulty. During the driving process of a car, if the water temperature gauge decreases, we can use the troubleshooting method to check it, find the plug of the water temperature sensor in the car, and then see if the water temperature gauge in our car can float up. If it doesn't float up, it means that the car wiring and water temperature gauge have failed. If it does, it means that the water temperature sensor has failed. You can go to the corresponding 4S store or car repair center for repair.

"If the pointer of the water temperature gauge remains stationary, in most cases, the instrument of the vehicle is damaged, and it is not possible to directly feedback water temperature data, or the response of the vehicle water temperature sensor bow is damaged, the feedback voltage is abnormal, or the vehicle circuit is loose, causing excessive resistance in the vehicle wiring, which can also cause the water temperature gauge to accumulate abnormally.". If the car is a liquid crystal display instrument, we can customize the display of car data. It is possible to define the liquid crystal instrument as a car fault state during the driving process of the car, so we need to manually adjust the buttons on the display and adjust it back.

The water temperature of the car drops as it runs . This situation is very normal , especially in winter when driving on high speed for a long time. The main reason for this problem is that vehicles are traveling at high speeds , and the wind can effectively improve the cooling effect of the intercooler , resulting in water temperatures hovering between 80-90 degrees . At the same time, it is not ruled out that the failure of the water temperature sensor has caused the coolant to remain in a large circulation state . If the water temperature suddenly drops sharply while driving, it is necessary to go to the maintenance factory as soon as possible to check whether the water temperature sensor has a fault . If there is a fault , it should be replaced in a timely manner , otherwise it will lead to increased engine wear .
