Abstract
An engine control system of a vehicle includes a first temperature module, a second temperature module, and an exhaust gas recirculation (EGR) control module. The first temperature module determines a temperature of gas within an intake manifold of an engine. The second temperature module determines a temperature of an EGR conduit that is coupled to the intake manifold. The EGR control module reduces opening of an EGR valve when the temperature of the gas and the temperature of the conduit is greater than a predetermined temperature.
