Acceleration Control - Overview

The acceleration controls consist of the accelerator pedal, APP sensor and bracket 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 to increase or decrease the 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 vehicle to be driven with limited performance.
