I have a 2008 expedition at around 189,00 miles I replaced the timing chain. I'm at 193,000 and I've been having a consistent issue. At about 192,000 the CEL came on and the codes were p0340 and p0344. I changed both camshaft position sensors and the code came back. I took the timing cover back off the engine just to double check that I did the timing right and it was good. I thought they could've been bad sensors because they weren't Motorcraft sensors so I bought Motorcraft sensors and put them in and the code was still there. I ended up taking it to Ford and they told me the issue was with my variable valve timing solenoid, so I changed both of those, and now I'm getting a P0020, P0340, and P0344. Also after I drive for about 20 mins the engine makes a ticking sound but it isn't constant. I'm at a loss for what the issue could be.
