Where is the EGR differential pressure sensor?
Where is the EGR differential pressure sensor? The EGR differential pressure sensor measures the exhaust gas pressure drop across the EGR differential pressure orifice. This pressure drop is used to calculate the amount of EGR flow into the intake manifold. ISM02 (CM870 and CM570) and ISM04 (CM875) engines: The sensor is located on the air intake manifold. How does the EGR pressure feedback sensor work? When the EGR pressure feedback sensor detects that the pressure is low, it will open up the EGR valve to increase flow, and just the opposite will close the valve if it detects that pressure...
