It sounds like you need to check the electrical connection to the camshaft sensor, and/or replace the sensor itself. With the engine rebuild, it's likely that it didn't get hooked up, or was damaged in the rebuild. You cannot clear the code, because as soon as you do, the ECU detects the problem again within a fraction of a second, and illuminates the check engine light again.
I no longer have a Jeep with the 3.8 engine, but hopefully, one of the other guys will be along to help you figure out where the camshaft sensor is and what it looks like so you can check it.
In the meantime a quick google for check "Jeep jk camshaft sensor" or "replace Jeep jk camshaft sensor" might get you on the right path. just make sure it applies to the 3.8 engine in your Jeep and not the 3.6 in the 2012 and newer ones.
