App Average

The scan tool displays 0-150 counts. If the accelerator pedal is fully depressed the scan tool will display approximately 122 counts. The Throttle Actuator Control (TAC) module takes the voltages from the 3 Accelerator Pedal Position (APP) sensors, averages the readings and converts the readings into counts. The scan tool displays the average. The average is different on every vehicle.
