2743 - P0155
| Information saved in | DME |
| Fault code | 2743 - P0155 |
| Fault text | Oxygen sensor heater resistance diagnosis before cat. converter, bank 2 |
| Fault description | O2 Sensor Heater Circuit (Bank 2 Sensor 1) |
| Condition for fault identification | Test condition: The upper or lower threshold of the resistance values has been violated, above/below 6.0 ohms (K_LSHVK_DIAG_RU) 14.5 ohms (K_LSHVK_DIAG_RO) |
| Terminal condition: Engine running | |
| Voltage condition: Battery voltage > 9V (k_ed_ubmin) | |
| Condition for fault memory entry | min. K_LSHVK_DIAG_ANZ_MESS (100) valid calculations of heater resistance - roughly.1.5 sec. |
| Action in service | 1. DME software release must be more recent than 07-06-510, fix incorporated since 07-09-521 |
| 2. Check plug, wiring harness on pre-cat oxygen sensor LSVK B2, | |
| 3. If OK, replace oxygen sensor | |
| Fault effect and breakdown warning | MIL lamp on after engine runs 2x /Small influence on drivability |
| Driver information | Warning light: MIL |
| Service instruction | None |
