P0016 - Cam and Crank correlation out of specification. This code is a PIA at times. It basically says that the camshaft and crank are out of time with each other but that difference can be very small. It usually is not a bad sensor as the computer uses those to determine if the code should be set.
In this case check the camshaft adjustment valve. (Adjuster for the cam timing) Be sure it has power first, battery voltage key on. Then unplug it and check the resistance across the terminals (5-9 ohms) if not in spec replace valve. If you have proper voltage at valve, proper resistance across terminals and good ground. Test the signal wire from the ECM to the control valve, 1 ohm or less resistance in that wire. If that all checks out the ECM has a fault.
A good scan tool to actually look at what the computer sees and even better a scope and known good waveform would tell you a lot.
