I have a 2014 Jeep Wrangler with 3.6L stock. I have been trying for weeks to repair this problem. Tech from a Jeep dealership gave me info I check everything and it ohms out correctly. The c121c code tells me to replace the ECU which is throwing parts at it. The p0344 code tells me to replace the passenger side cam sensor. But it also gives me a torque denial code. Then it will go into limp mode and the check engine light will go on and the traction control light with the abs light goes on. It seems to do it the warmer it gets outside, when it is a cooler morning it will act fine. Any info that will help
Thanks
 
Theres a TSB out for this issue, 18-053-15 granted it's for RHD jeeps so it might not be applicable but just worth a shot to read it. That c121C code is gonna be triggered by any sort of P code, you need to attack the p0344 because that's what's gonna be dragging everything else down. If you have access to a scan tool look at your requested and actual position of the camshaft, it can very well just be the cam sensor, which isn't hard to replace and might cost you a $100 or so bucks. If say you do that and it doesn't do anything, a scanner will need to be used to figure out whether the camshaft isn't giving a signal to the cam sensor, or if the OCV is stuck or sticking.

Thank you for the tsb I had checked at the connector but didn’t go back that far into the harness.
 
I recently replaced both cam position sensors and the crank position sensor. They were easy to replace, but the crank position sensor was the easiest.

At the dealer I paid $52 each for cam position sensors and $25 for crank position sensor.

I heard aftermarket quality on these items sucks.

I just Ed to clarify that OEM sensors are not expensive and I am not suggesting what I recently changed is what is wrong with your Jeep.
