273A - P2271
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 |
273A - P0136
273A - P0136 | | Information saved in | DME | Fault code | 273A - P0136 | Fault text | Oxygen sensor vibration check behind catalytic converter, bank 1 | Fault description | O2 Sensor Circuit (Bank 1 Sensor 2) | Condition for fault identification | Test condition: Oxygen sensor signal too low, lower than 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 | 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 B1 | Fault effect and breakdown warning | MIL on after engine runs 2x | Driver information | Warning light: MIL | Service instruction | None |
273A - P013E
273A - P013E | | Information saved in | DME | Fault code | 273A - P013E | Fault text | Oxygen sensor vibration check behind catalytic converter, bank 1 | Fault description | O2 Sensor Delayed Response - Rich to Lean (Bank 1 Sensor 2) | Condition for fault identification | Test condition: * Determine whether oxygen sensor voltage remains above 151 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 | 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 | | 2. If OK, replace post-cat oxygen sensor LSNK B1 | Fault effect and breakdown warning | MIL on after engine runs 2x | Driver information | Warning light: MIL | Service instruction | None |
273A - P2270
273A - P2270 | | Information saved in | DME | Fault code | 273A - P2270 | Fault text | Oxygen sensor vibration check behind catalytic converter, bank 1 | Fault description | O2 Sensor Signal Biased/Stuck Lean (Bank 1 Sensor 2) | Condition for fault identification | Test condition: Trim control suspicion with observation of P component and I component laeds 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.
