Okay. The P0171 and P0174 are lean codes saying that you have more oxygen in the exhaust then expected. Below is a guide going through the detail on this.
P0016 is a cam and crank misalignment code.
P0341 - is a cam sensor fault.
I would suggest running through the P0341 then the P0016 diagnostic because the lean exhaust could be a result of these.
I know you put a cam sensor in it but that is not the only cause of these codes. You will need to perform the tests that are detailed in order to find the cause. Unfortunately, if we don't we will just be guessing.
