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
