Ok I hope someone can offer me some advice. I have my 2011 JK throw the camshaft position sensor code P0016. I have replaced sensor, and plug. Not working. Here is the weird part. If I clear the code I can drive it as long as I want with no issues. It’s runs as it should. When I turn the Jeep off and restart it the code throws again.

 

Check and clean and grease all grounds first. There are about 4 in the engine bay plus the battery connections. That is always a good place to start.
