My 2008 Dodge Avenger SXT (2.7L, V6) keeps getting this code. I have found very little info online about what this could potentially mean, and I am trying to go without paying to get anything fixed if I don't have to at the moment. Does anyone have experience with this particular code and what happened when you either had it fixed? I've gotten a few opinions but most of them are vague (saying that it could be as simple as cleaning the sensor itself all the way to having to replace the entire manifold). My car runs fine and I've not seen any difference in fuel economy, which is apparently a potential issue.
