2012 JK crankshaft positioning sensor plug problems

Yes I bought it from jeep so u don’t think it the plug po339 is the code


A bad connection, a bad wire that has rubbed the insulation off, and or a faulty Sensor. Just need to inspect the connector close and follow the wires and check for a spot that they could be bad.
 
I also canceled the cold runs good at low speed up past 60 it appears to be losing power or doing something weird


There was a few years of the JK's that the underhood insulation was being sucked down over the air filter intake and causing a problem at highway speeds or fast acceleration.
