so from researching, and posting on different forums cant find any solutions... what i've figured out and a fellow fourtituder said that my timing could be off at the bank for which this code is on, in this case bank 2.. if the chain is off by a link could that be adjusted from the head or i need to redo the timing belt job...??? .......(recently did a timing belt job valve cover gaskets, seals, and tensioner gaskets...a p0346 code came up, i erased it and if the car runs the CEL stays off, but if i shut the engine off and restarted CEL comes back on,, i tried replacing the position sensor with a oem one, but no difference. ) help is really appreciated,
