Abstract
A method of controlling an engine of a vehicle having a particulate filter and operable in an air restriction mode wherein air inflow to an air intake throttle is restricted includes determining if the engine is operating in the air restriction mode, sensing a position of an accelerator pedal, and sensing a speed of the vehicle. The method further includes removing the restriction to the air intake throttle when the engine is operating in the air restriction mode, one of a change in position of the accelerator pedal over a period of time is greater than a pre-defined pedal acceleration rate or the position of the accelerator pedal is equal to a pre-defined pedal limit, and the speed of the vehicle is less than a pre-defined speed limit.
