273B - P2273
| Information saved in | DME |
| Fault code | 273B - P2273 |
| Fault text | Oxygen sensor vibration check behind catalytic converter, bank 2 |
| Fault description | O2 Sensor Signal Biased/Stuck Rich (Bank 2 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 B2 | |
| Fault effect and breakdown warning | MIL on after engine runs 2x / no effects on drivability |
| Driver information | Warning light: MIL |
| Service instruction | None |
273B - P0156
| Information saved in | DME |
| Fault code | 273B - P0156 |
| Fault text | Oxygen sensor vibration check behind catalytic converter, bank 2 |
| Fault description | O2 Sensor Circuit (Bank 2 Sensor 2) |
| Condition for fault identification | Test condition: Oxygen sensor signal too low, low threshold 649 mV (K_LANK_OBD_S_VL_US) for 2 (K_LANK_OBD_S_CNT) /K_LANK_OBD_S_AUTOM_CNT requests |
| Terminal condition: Engine running | |
| Voltage condition: none | |
| Condition for fault memory entry | Full-load K_LANK_OBD_S_VL_T (6s) for K_LANK_OBD_S_CNT (3x) /K_LANK_OBD_S_AUTOM_CNT (3x) attempts |
| Action in service | 1. Check exhaust system for leaks |
| 2. If OK, replace post-cat oxygen sensor LSNK B2 | |
| Fault effect and breakdown warning | MIL on after engine runs 2x |
| Driver information | Warning light: MIL |
| Service instruction | None |
273B - P014A
| Information saved in | DME |
| Fault code | 273B - P014A |
| Fault text | Oxygen sensor vibration check behind catalytic converter, bank 2 |
| Fault description | O2 Sensor Delayed Response - Rich to Lean (Bank 2 Sensor 2) |
| Condition for fault identification | Test condition: * Determine whether oxygen sensor voltage remains above 649 mV (K_LANK_OBD_S_SA_US) |
| * Fault after 2 (K_LANK_OBD_S_CNT)/K_LANK_OBD_S_AUTOM_CNT attempts | |
| Terminal condition: Engine running | |
| Voltage condition: none | |
| Condition for fault memory entry | Time K_LANK_OBD_S_SA_T (3s) after SA for K_LANK_OBD_S_CNT (2x) /K_LANK_OBD_S_AUTOM_CNT (3x) tries |
| Action in service | 1. Check exhaust system for leaks |
| 2. If OK, replace post-cat oxygen sensor LSNK B2 | |
| Fault effect and breakdown warning | MIL on after engine runs 2x |
| Driver information | Warning light: MIL |
| Service instruction | None |

| Information saved in | DME |
| Fault code | 273B - P2272 |
| Fault text | Oxygen sensor vibration check behind catalytic converter, bank 2 |
| Fault description | O2 Sensor Signal Biased/Stuck Lean (Bank 2 Sensor 2) |
| Condition for fault identification | Test condition: Trim control suspicion with observation of P component and I component leads to guided RICH 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_F_CNT (1x) RICH control events the oxygen sensor sticks at LEAN |
| Action in service | 1. Check exhaust system for leaks |
| 2. If OK, replace post-cat oxygen sensor LSNK B2 | |
