260A, 261A, 271A

[007]

Hello,

I have these 3 codes on my 2004 T6 XC90, my scanner says ¨long-term fuel trim¨ and ¨adaptive lambda control, bank 2¨ (this is for the 271A). This is the second time they displays, first time was 4 weeks ago, and simply ¨erased¨ from the scanner, but now it came back again.

I really don´t know what the codes mean, so I would like to know if someone knows the solution to permanently erase these codes? what do I have to replace or check?

Thanks for your replies!
