Check Engine Light p0303 and p0344

[Jay MacLeay]

Recently my check light came on. I read the codes and I'm getting a p0303 and p0344. The light has been going off and then coming back on. Now when it comes on it's sending the Jeep into limp mode, but if I turn the Jeep off and start it again it's fine. I replaced the opda a year because of the p0344 and p0340 codes (it solved them). I also did the tsb that calls for the heat shielding around cylinder 3 injector (which solved that issue). Any help would be greatly appreciated.

When you replaced the OPDA, did you reuse your stock sensor or the one that came with the OPDA?

Pretty sure I used the stock one, but I can't remember exactly.

A lot of people report issues with the sensors that come with aftermarket OPDAs, may be worth checking.

This is VERY similar to what my Rubi is doing. Have had the p0303 code twice...
