Bank 2 pre-catalyst oxygen sensor pumping current calibration error
Engine temperature > K_LAVK_OBD_TMOT * Sensor temperature > K_LAVK_OBD_VK_TEMP * since recognition of overrun an air mass flow of K_LAVK_OBD_SA_ML_SUM must have occurred
Oxygen sensor is available, sensor voltage > K_LAVK_OBD_SA_DIAG_OL
1. Check plug and wiring harness to pre-catalyst oxygen sensor forward of Bank 2 catalyst (especially IA trim wire)
2. If OK, replace oxygen sensor
Replace that oxygen sensor, clear faults and see if any return.
