The CEL went of today, and I was a litle bit confused, has my car a self repair function? So I went to autozone again, they checked it and the mesagge PO133 still comes, it also says 'slow response'. At autozone the part costs 61$, 10$ more then at the link above, but they will lend me the socket for for replacement but not a wretch. So I think I wil get it from autozone and try to borow a wratch.
But can it be that the sensor is 'only' dirty, and after cleaning it would work again? 'cause if it would be broken it wouldn't say slow response but no response, or not?
