Cause of engine jitter (abnormal water temperature sensor)

Cause of engine jitter (abnormal water temperature sensor) :

Whether the running state of the engine is good is usually judged by the water temperature sensor. If the information of the sensor is wrong (usually manifested as the difference between the information transmission temperature and the real temperature of the outside world), it will lead to the abnormal injection of the engine injector, and the jitter problem is inevitable.
