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.

A lubrication torque limit module includes a temperature module that determines a temperature of an engine and generates an engine temperature signal. A limit module generates a torque limit signal based on the temperature signal and a speed of the engine. The torque limit signal identifies an indicated torque maximum limit. A torque arbitration module limits indicated torque of the engine based on the indicated torque maximum limit. The indicated torque of the engine is equal to an unmanaged brake torque of the engine plus an overall friction torque of the engine.
