Description

The diagnostic method of the water temperature sensor analyzes the collected electrical signal of the water temperature sensor to determine whether the water temperature sensor signal is wrong and reliable, including the rationality detection of the water temperature sensor signal range and the dynamic detection of the normality of the output signal of the water temperature sensor. It checks the signal range of the water temperature sensor to determine whether the output signal of the water temperature sensor is within a reasonable range. When the signal is within the specified range, it determines whether the actual output signal matches the output signal corresponding to the current actual water temperature. The diagnostic method of the water temperature sensor detects and analyzes the collected voltage signal of the water temperature sensor to determine whether the output signal of the water temperature sensor is valid and accurate. Analyze the collected electrical signal of the water temperature sensor to determine whether the water temperature sensor signal is wrong and reliable. Because the control unit of the engine needs to compensate and correct some parameters of the engine according to the water temperature, and the signal sent by the water temperature sensor has a certain range requirement. Therefore, it is necessary to check the signal range of the water temperature sensor, and the output signal of the water temperature sensor must be within a reasonable range. At the same time, if the signal is within the specified range, it must also be ensured that the actual output signal is consistent with the output signal corresponding to the current actual water temperature, otherwise it should also be an error. The rationality detection of the output signal range of the water temperature sensor is used to judge whether the water temperature sensor fails. Under the premise of satisfying the rotational speed and fuel injection quantity, the minimum temperature rise value and delay time are calculated according to the current water temperature. After the delay time expires, whether the temperature rise value reaches the minimum temperature rise, so as to judge the signal of the water temperature sensor. Is it accurate.
