Abstract
An exhaust gas recirculating valve includes a body, a closure member, a magnet, and a magneto-resistive sensor. The body defines a passage through which exhaust gas flows. The body includes a seat and the passage includes an aperture defined by the seat. The closure member is displaced between first and second configurations with respect to the seat. The first configuration sets at zero percent a percentage of exhaust gas that flows from an exhaust manifold of an internal combustion engine to an intake manifold of the internal combustion engine, and the second configuration sets atpercent the percentage of exhaust gas that flows from the exhaust manifold of the internal combustion engine to the intake manifold of the internal combustion engine. The magnet moves congruently with the closure member, and the magneto-resistive sensor detects the movement of the magnet so as to determine the percentage of exhaust gas flow.
