The differential pressure sensor is a sensor designed based on MEMS technology to measure the gas pressure difference between the DPF and GPF ends of the car to reduce exhaust emissions and protect the environment. The pressure sensor outputs a voltage signal that is linearly proportional to the pressure and provides accurate and stable signal output and temperature compensation.
