P2592 Cruise Control Front Distance Range Sensor Right

P2592 marks a fault of the right-hand front distance sensor in multi-radar adaptive cruise layouts; the left unit reports P2591, a single or centre radar P2583. No maker publishes this code. Compared with a radar behind the grille emblem, a right corner sensor is more exposed to kerb and parking contact, stone chips and road salt reaching its connector, and it is often disturbed when a bumper is replaced on the passenger side. That is why aiming and mounting are checked before parts are swapped. Honda's P2583 bulletins illustrate the usual chain: dirt or ice on the radar face leads to a misalignment report and a temporary shutdown of the assistance. The engine module only keeps the record; the detailed cause is stored in the driver assistance or radar module. Driving itself is unaffected.

Likely causes

Right sensor knocked out of alignment by kerb or parking contact
Road salt or water corrosion at the right sensor connector
Sensor not recalibrated after bumper replacement
Right radar sensor internally faulty

Symptoms

  • Adaptive cruise control switched off
  • Warning message for the radar or driver assistance system
