Okay, so I have a question, my service engine light came on about two weeks ago and it was a p0016 code. I have replaced both the crankshaft sensor and the camshaft sensor but the engine light is still on for the p0016 code. It drives perfectly fine, no issues what so ever. So just looking for suggestions on what else to try besides replacing the timing chain because that is my next thing to do if nothing else works. I have the car listed above LT model.

P0016 is telling you that there is a problem in the timing system, either the chain is worn or jumped time a bit.
It will not be the sensors themselves as the code shows they are working and the engine is running okay.
Basically the code means that the camshaft and crankshaft are out of time with each other enough that it is causing a problem. Not an uncommon thing these days. The repair is a new timing set and be sure to replace the guides and tensioner. As it is saying the cam chain is bad you will want to replace the balance shaft chain as well as it will have the same wear amount.
