274A - P2626
| Information saved in | DME |
| Fault code | 274A - P2626 |
| Fault text | Oxygen sensor pump current calibration fault before cat. converter, bank 1 |
| Fault description | O2 Sensor Pumping Current Trim Circuit/Open (Bank 1 Sensor 1) |
| Condition for fault identification | Test condition: Oxygen sensor is available, oxygen sensor voltage > 4951 mV (K_LAVK_OBD_SA_DIAG_OL) |
| Terminal condition: Engine running - overrun condition | |
| Voltage condition: None | |
| Condition for fault memory entry | after a defined SA phase the lag period K_LAVK_OBD_SA_T (2.5 sec) must be completed |
| Action in service | 1. Check plug and wiring harness on pre-cat oxygen sensor LSVK B1 (especially trim circuit wire IA), |
| 2. If OK, replace oxygen sensor, replace DME as indicated | |
| Fault effect and breakdown warning | MIL lamp on after engine runs 2x /Small influence on driveability |
| Driver information | Warning light: MIL |
