I have a 2008 JKU and am throwing code P0344. I don’t have a scope tester but I am getting a good ground and 5v at both the crank and cam sensor. I will be driving down the road then out of nowhere get the traction control light. Then the Jeep will go into like a engine “limp mode” with the low voltage light and hardly enough power to drive. Sometimes I can shut it off then on again and drive normal for maybe a mile or 2 if I keep RPM’s up. Please help

 

Hi and welcome!

I'm moving your thread to a tech forum where fellow owners should be able to help. Good luck!

Likely the camshaft position sensor needs to be replaced, but here's a pretty good diagnosis video.

 

I have replaced the sensor...4 times. I’ve tested the sensor and it functions properly

 

How about the battery and connections- they're tight and corrosion free as well as a healthy battery? The jeeps act funny with dead/ deathbed batteries.
