The commanded throttle position (TP) is compared to the actual TP based on accelerator pedal position (APP) and possibly other limiting factors. Both values should be within a calibrated range of each other. The powertrain control module (PCM) continuously monitors the commanded and the actual throttle positions. This DTC sets if the values are greater than the calibrated range.
