Circuit Description
WARNING: This page is about a different variant/trim than selected.
The commanded throttle position (TP), based on accelerator pedal position (APP), is compared to the actual throttle position. The TP 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 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.
