P1512 BUICK Meaning

The commanded throttle position is compared to the actual throttle position based on accelerator pedal position 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 Diagnostic Trouble Code (DTC) sets if the values are greater than the calibrated range.
