I have a 2012 JK, which while I drive it in the city 20-40 Miles/Hour does not show me any errors, but if I accelerate to 60+ ....it shows me the following errors:
P0394: Camshaft position sensor B circuit intermittent (Bank2)
P0420: Catalyst System efficiency below threshold (Bank1)
P2638: Torque Management feedback signal A range/Performance.
I already changed the 2 camshaft sensors, I'm waiting for the O2 sensors from Mopar.
Any idea what is going on?

in my 07 there is a pack of grounds bolted to the right side of the block.
controlls tons of things, including the O2 sensor.
Seems to be a common thing where those get corroded pretty badly.

I would start with all of the grounds you can find along the frame of the engine bay, Jeep was nice and mounted them nice and high and easy to find.

on my JK with the 3.8, that pack of grounds going to the side of the engine block was all sorts of corroded.
Not what I would call "Bad, but I had to cut up pretty far on each one of those wires to find copper-colored wires.
then I spliced in a big fat extension from there using some 8 gauge I had laying around.

I'll try checking the Grounds..
Thank you JFish'n
