P2591Cruise Control Front Distance Range Sensor Left
- Generic OBD-II code · Powertrain
- How the car detects it
- P2591 is reserved for the left front distance sensor in cruise systems that combine several radars across the front; a single or centre unit uses P2583 and the right one P2592. No manufacturer documents P2591 publicly. Honda's bulletins on P2583 show what such a sensor typically reports: a view blocked by ice or dirt, or a misalignment the unit detects itself. A left corner sensor sits behind the bumper cover, so parking knocks, a repainted or replaced bumper, thick paint over the sensor area and bent brackets are prime suspects, before wiring or the sensor itself. CARB cites a cruise control that turns itself off on a detected fault as a diagnostic without emission impact, so a check engine lamp is not to be expected. Adaptive cruise and related assistance remain unavailable.
