Abstract

The invention relates to a detecting device of a water temperature sensor and a detecting method thereof, comprising a transparent container, an approach slab, a heating device and a thermograph; wherein, a main body consisting of the transparent container and the approach slab is filled with water, the heating system and the thermograph are arranged on the approach slab and contacted with the water, an air outlet hole is arranged on the approach slab, and another hole is arranged on the approach slab and is used for installing the water temperature sensor. The invention can rapidly and accurately identify whether the water temperature sensor is invalid or not.

Description

technical field [0001] The invention relates to a detection device for a water temperature sensor, which is suitable for an engine bench test, and also relates to a method for detecting a water temperature sensor. Background technique [0002] In the engine bench test, the water temperature sensor is a very sensitive electronic component. If the water temperature sensor fails, it will give wrong water temperature feedback to the ECU, which will lead to a misjudgment by the ECU, thereby reducing or increasing the fuel injection volume, resulting in a wrong control mode , causing the engine to malfunction. When the fuel injection quantity decreases and increases, many other phenomena will occur, so that the test personnel often cannot find the cause quickly when troubleshooting, and waste a lot of time and energy. In the past, we often can only judge whether it is the problem of the water temperature sensor by replacing the wiring harness or replacing the new water temperatur...
