DTC P1516: Commanded Vs. Actual Throttle Position Performance (TAC Module): Description

The commanded throttle position is compared to the actual throttle position 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 actual throttle positions. This DTC sets if the values are greater than the calibrated range.
