- 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).
- 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.

Diagnostic conditions
- Short drive more than 10 seconds
- Lambda control active
- Vehicle not in overrun phase
- No fault entered for : Oxygen sensor(s) or Fuel/air mixture preparation
