Information saved in	DME
Fault code	2751 - P112D
Fault text	Oxygen sensor fault pump current cable before catalytic converter, bank 2
Fault description	O2 Sensor Negative Current or Positive Current Control Circuit/Open (Bank 2 Sensor 1)
Condition for fault identification	Test condition: Lambda factor lies within this range 1.001 (K_LAVK_OBD_PLAU_LAM_MIN) and 1.009 (K_LAVK_OBD_PLAU_LAM_MAX) and the post-catalyst lambda is still outside the range 88 mV (K_LAVK_OBD_PLAU_LANK_MAX) and 879 mV (K_LAVK_OBD_PLAU_LANK_MIN) OR oxygen sensor voltage
.	Terminal condition: Engine running - Condition idle or part-load
.	Voltage condition: none
Condition for fault memory entry	none
Action in service	1. Check plug and wiring harness on pre-cat oxygen sensor LSVK B2 (especially IP pumping current),
.	2. 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
