From Wiki-DIY
273A - P2271
| Information saved in | DME |
| Fault code | 273A - P2271 |
| Fault text | Oxygen sensor vibration check behind catalytic converter, bank 1 |
| Fault description | O2 Sensor Signal Biased/Stuck Rich (Bank 1 Sensor 2) |
| Condition for fault identification | Test condition: Trim control suspicion with observation of P component and I component leads to guided LEAN control; if the post-cat oxygen sensor signal fails to respond accordingly, the error is assigned to the post-cat oxygen sensor |
| Terminal condition: Engine running | |
| Voltage condition: none | |
| Condition for fault memory entry | After K_LAVK_OBD_ACT_NK_M_CNT (1x) LEAN control events the oxygen sensor remains stuck at RICH |
| Action in service | 1. Check exhaust system for leaks |
| 2. If OK, replace post-cat oxygen sensor LSNK B1 | |
| Fault effect and breakdown warning | MIL on after engine runs 2x / no effects on drivability |
| Driver information | Warning light: MIL |
| Service instruction | None |

| Condition for fault memory entry | Full-load for K_LANK_OBD_S_VL_T (6s) for K_LANK_OBD_S_CNT (2x) /K_LANK_OBD_S_AUTOM_CNT (3x) attempts |
| Action in service | 1. Check exhaust system for leaks |
