Hey everyone! New member here. Just wondering if anyone has run into the P0344/P0369 engine code issue.
The code trips if I'm at highway speeds (120 Km/hr) in 6th gear (sometimes) if I use cruise control I can gaurantee the code trips!
I've run out of warranty on 2014 Jeep Wrangler Sport and have had sensors replaced, wiring checked, and the oil pan screws checked!
I've had it in over 10 times trying to get this resolved, a buddy of mine that used to work for a Dodge dealer says its probably the timing belt!
Anyone else had any success in getting rid of these codes for good!
I want be able to use my cruise control at highway speeds again!

 

I had the PO355 and in fact still get it now and then. I keep clearing it with my OBD2 gadget as its not something to worry about
Take off ur gas cap and clean the rubber gasket and make sure it is put back tight. Many times for that po that is all that is wrong.
It does say a sensor also but that one is going to be a bugger to remove and one might end up having to replace some exhaust
piping as its not coming off easy. The PO369 I haven't had that one come up
