Q: What does code P1563 mean?

Cruise Vehicle Speed Set Speed Difference Too High. P1563 on Chrysler vehicles means the powertrain control module (PCM) has detected that the actual vehicle speed reported by the speed sensor differs too much from the speed the cruise control system is trying to maintain. The PCM sets this code when the measured speed deviates from the set speed by more than a calibrated threshold for a sustained period, indicating a fault in the speed signal or cruise control servo circuit.
