I have a 2015 jeep Cherokee 3.2L with codes p0019 & U1424, car came to the shop with the p0019, so I did the camshaft position sensor on both sides, swap the solenoids to see if the code follows it didn't, I did the timing chain and the crank sensor, after the timing chain i got u1424 in the transmission and it goes into a limp mode, at this point I don't know what else to do. Does any body have deal with something similar.
