P2AD3Throttle/Pedal Position Sensor/Switch A/G Voltage Correlation

P2AD3 indicates that the engine control module (ECM) has detected a mismatch between the voltage signals from throttle position sensor or pedal position sensor 'A' and 'G' over a calibrated time period. The ECM expects these two signals to correlate within a tight tolerance, and when the difference exceeds the threshold, it stores this code and illuminates the check engine light.
