P2567 Direct Ozone Reduction Catalyst Temperature Sensor Circuit

Drive cycleNot required

P2567 is the general circuit fault of the sensor fitted to a direct ozone reduction (DOR) radiator - a radiator with a catalytic coating that converts ground-level ozone in the passing air and earns low-emission vehicles an NMOG credit. CARB section (e)(14) requires the OBD system to detect a missing or deteriorated DOR function. No manufacturer publicly documents P2567 itself. VW's 2014 books (CC, Tiguan) use the siblings P2568-P2570 for this sensor, with an identity check and LIN bus faults; MINI's 2015-2016 Cooper S with the B46M PZEV engine carries a LIN-linked catalyst sensor fixed to the radiator, logged under BMW's own fault codes. P2568 is the plausibility fault, P2569-P2571 low, high and intermittent. Often the radiator with its bonded sensor is replaced.

Likely causes

Failed radiator identification/temperature sensor
Damaged sensor wiring or connector at the radiator
Replacement radiator without coating or without sensor fitted

Symptoms

  • Check engine light
  • No change in driveability or engine cooling
  • Possible failed emissions inspection because of the stored code
