Ford Fusion: Acceleration Control / Acceleration Control - Overview. Description and Operation
Overview
The acceleration controls consist of the accelerator pedal and sensor assembly.
The throttle is controlled by an APP sensor on the accelerator pedal assembly. The APP sensor sends a signal to the PCM in response to throttle pedal movements initiated by the driver. The PCM sends a signal to the electronic throttle control which increases and decreases throttle position.
The
engine management system electronically operates the throttle of the
engine in response to throttle pedal movements initiated by the driver.
In the event of a system failure, the engine management system provides a
"limp home" mode which allows the car to be driven with limited
performance.
