The timing belt was changed at 115,000, the car now has 235,000, I got the P0016 code about crank and cam sensor, I changed both sensors, but still get the same code. I did not touch the CVVT hub,( do not where it is). However, this all stated a few miles after I left the AC shop where they worked ...

The cam and crank sensors have been replaced and the computer is still posting the P0016 code. Also the car is running like it is not timed correctly. Any comments about how to correct this problem.
