Good Evening Gentle Cars! Yesterday my jk went into limp mode after turning onto another road and began giving the codes listed below. Any guidance would be an amazing help. I may be wrong but this looks like i have somewhat of a power issue somewhere. I had to replace coil packs and the PCM earlier this year.


P0652 - Sensor Reference Voltage 2 Circuit Low
P0934 - Line Pressure Sensor Circuit Low
P0405 - Egr Position Sensor Circuit Low
P0340 - Camshaft Position Sensor Circuit
P2127 - Accelerator Pedal Position Sensor 2 Circuit Low

Sounds like a damaged wiring harness or pcm. That's a lot of random unrelated codes. Check all of your main harnesses for rodent damage or rubbing. Especially since it happened while turning. Any recent repairs done on vehicle?

Simple things first, check, clean, and re tighten all the battery cables and connections.
Loose wires cause low voltage which can result in random errors.
