DTC codes / P25xx · Vehicle speed, idle control and auxiliary inputs / P2583
P2583 indicates that the cruise control system's front distance range sensor, either a single sensor or the center sensor in a multi-sensor arrangement, has reported a fault or its signal is outside the expected range. The powertrain control module (PCM) or cruise control module monitors this sensor to maintain a safe following distance, and it sets the code when the sensor's data is implausible, missing, or indicates an internal failure.
Guidance is general and written for all OBD-II vehicles. Exact tests and values vary by model, so confirm the fault before replacing parts.
