Patent abstract
Methods and systems are provided for detecting throttle obstructions in a vehicle. In one example, after engine start up, throttle icing condition resulting from the throttle capturing ice fragments originally formed within a charge air cooler or an intake passage upstream of throttle, may be detected. Responsive to detecting the throttle icing condition, the throttle may be adjusted to a fully open position independent of accelerator pedal position, and maintained at the fully open position for a threshold duration while maintaining a desired torque, to release the captured ice fragments from the throttle.
