It's possible that it could get some corrosion on the terminals, but for the most part they are usually water tight.

I put a new sensor and worked good for a while and then it kicked out the same code

Was it a Mopar sensor, the JK's are real picky about what gets put on them.

I also canceled the cold runs good at low speed up past 60 it appears to be losing power or doing something weird

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.

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.
