Check engine light on

[Samou]

I purchased my first 2009 cobalt sedan 2.2 with 133k mile,it start run and drive but it seems consuming a lot of gas.about half tank in 120 mile,the check engine light is on,I did a scan and I get a p0017 code I replaced the camshaft sensor and did an oil and filter change but the light won't go away.it comes back every time I erase it.
Any ideas?

P0017 can also be caused by the cam sensor actuator. Did you replace the correct camshaft sensor? There are two.

That fuel consumption sounds normal to me. 240miles to a tank sounds downright nice, but then I've got the 2.0 Turbo and a heavy foot.
