Abstract
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...
