1/8 npt water temp sensor and gauge

• 2022-10-09

Our water temp gauge sensor include the 1/4 npt and 1/8 npt. They are different standards. Customers can choose which is match to their water temp gauge. The working performance of the automobile water temperature sensor has a great influence on the fuel injection quantity of the engine, and then affects the combustion performance of the engine. When the mixture is too rich or too lean, the combustion of the engine will deteriorate, which will cause the engine to be difficult to start and run smoothly. At this time, check the water temperature sensor. To detect the automobile water temperature sensor, we must first understand the principle, structure and composition of the automobile water temperature sensor.

The automobile 1/8 npt water temp sensor assembly generally consists of three parts: gasket, water temperature sensor and wire connector. When the water temperature sensor fails, it usually displays the temperature signal of "yes" when the engine is cold started. The signal of "no rich mixture" is not available for EC, but only the thinner mixture of the engine (the signal when the engine is hot). Therefore, it is not easy to start the engine when the engine is cold. In this case, check whether the water temperature sensor plug contacts normally or replace the water temperature sensor. For example, reading the data of the static engine of the vehicle (referring to the cold car), it is found that the coolant temperature output by the engine ECU is 105 ℃, while the actual temperature of the engine (set as the temperature in winter) is only 1 ℃, which is obvious. The water temperature signal received by the engine ECU is incorrect, indicating that there is a problem with the water temperature sensor.

It should be noted that the sensor is a kind of electronic original device on the automobile circuit. If the device is broken, there is little room for repair, and it has to be replaced. If you want to test, the simple method is to put the water temperature sensor into the heating cup (do not submerge the plug part), and use the "resistance gear" of the multimeter to measure. When the temperature rises, the resistance should be smaller. If there is no change, it means that this thing is broken. When 1/8 npt water temp sensor and gauge are broken , you can contact us to buy them to replace.
