Circuit Description

The commanded throttle position, based on the accelerator pedal position (APP), is compared to the actual throttle position. The throttle position values should be within a calibrated range of each other. The throttle actuator control (TAC) module monitors the commanded and actual throttle position. If the TAC module detects that the commanded and the actual throttle positions are not within a calibrated range of each other, a message is sent to the powertrain control module (PCM) across serial data and DTC P2101 is set.
