Analysis and Improvement of Abnormal Problem of Differential Pressure Sensor Signal Measurement
In order to realize the regeneration and recycling of DPF,a differential pressure sensor is installed on the DPF.As a sensor to monitor the status of DPF,the accuracy of pressure differential sensor signal meas-urement directly affects the function of DPF.This paper analyzes and discusses the problem of engine bright fault light caused by abnormal signal measurement of DPF pressure difference sensor,and points out the fault cause and solution of abnormal signal measurement clearly through test verification.
