P1126

Oxygen Sensing Adaptation, Lower Load Range, Bank 1 (FRAU1) - Above Limit Value

NOTE:
- This fault is a supplement to fault code P2177.
- For LEV vehicles (USA) it is possible that 2 different mixture adaptation faults (one in RKAT and one in FRAU) activate the "check engine lamp (MIL)" after only one single occurrence. This is a checksum error.
