2014 JKU stuck in limp mode

Hello all, new to the forum, I've been struggling with what started as an intermittent issue but now happens all the time. I've got a 2014 JKU, I bought it with 75k on it from a local dealer certified preowned. The dealer was ok in the beginning, I had a water leak[ 3 times in they never fixed that} oil filter housing leak they replaced, then an issue when it would go into limp mode, they ordered and replaced the oil pump and all was well for about 6 months, when it started again I brought back and they said this was odd but replaced pump again, 4 days later and out of warranty it started again, I called, dropped it off and this time was told its not the oil pump, its something else and would need 3 to 4 hours labor to pull apart my timing cover to dig deeper into what's going on, I told them to button it up and ill take it home. the first codes I got were for bank 2 cam position sensor, I checked for 5 volts dc at pins 1,2&4 and ground at pin 3, all good, so I replaced the sensor, took it down the road and the dash lit up, checked codes and got bank 1 sensor, so I just replaced it, took for a ride and same thing, this time code 0344 and C121C, torque request denied. now I'm reading it may
be a crank sensor. Could someone help me out here, I'm all about diagnostics but nothing is making sense to me, plus Ide like to have my jeep back.

Any electrical parts that are being installed are they OEM, it is known that the Jeeps are real picky about the parts that are put on them.

Low transmission fluid is known to cause problems.

Dirty, loose, broken ground wires and battery clamps can cause problems.

A weak battery can also cause problems.

After doing any electrical R&R was a reset done on the ECM so that it could relearn?

Thanks for responding, I did not use OEM, I got mine from Napa, standard transmission, no leaks, Ill check the leval but im assuming your talking about an automatic. all my cables are clean and tight, how many grounds and where are they?? Battery is at 12.6 VDC, After I completed my repairs I cleared my codes with a super chip code reader.
