    x2 that that code should tell ya which is bad...but strongly suggest doing yourself a big favor and replace them all. If one's bad the others aren't far behind, or probably are bad just not enough to trip a code yet.

    Most likely the front one.... as they're closer to the hot gasses of the engine.

    Did you get the codes pulled from the dealer? They should be able to tell you which sensor it was....
