a mechanic did a test with a scanner and tells me that a sensor is failing, I did the test with my multimeter and I get these codes:

KOEO: 34, 67
KOER: 41, 91, 34

I changed the oxygen sensors in 2006, perhaps already finished its useful life?

Never can tell with those things man. Sometimes they last 100K miles. Other times... Not so much.

Erase the codes, drive for a few days and run them again.
