  Diagnosis information - DME V6 DFI

  
  

  Oxygen sensor ahead of catalytic converter, bank 1, dynamic response

  
  

  NOTE: Do not use contact spray on the oxygen sensor's plug connections as this will result in irreparable damage to the lines (blockage of reference air duct).

  
  

  NOTE: Do not interchange the oxygen sensor ahead of catalytic converter with the sensor behind the catalytic converter as this will result in implausible fault entries.
