Abstract
An automotive exhaust gas recirculating (EGR) system contains a pressure sensor responsive to the changes in exhaust manifold gas pressure to control the movement of an EGR valve. A water vapor/ice condenser is installed in the exhaust gas signal line to the pressure sensor so that any water vapor/ice present in the exhaust gas will be condensed/precipitated out and not cause a malfunction of the pressure sensor and an erroneous output signal.
