The throttle actuator control (TAC) system delivers
improved throttle response and greater reliability
and eliminates the need for mechanical cable. The
TAC system performs the following functions:

•  Accelerator pedal position (APP) sensing
•  Throttle positioning to meet driver and engine
•  Throttle position (TP) sensing
•  Internal diagnostics
•  Cruise control functions
•  Manage TAC electrical power consumption

The TAC system includes the following components:
•  The APP sensors
•  The throttle body assembly
•  The powertrain control module (PCM)
