Expert:  Stonyman replied 4 years ago.

It could be a bad cam sensor, your voltages are good, but the out of sync code can be a tough one. You need an oscilloscope to test the square wave pattern. This code can be a sensor, timing chain, or the most common, a bad flex plate. When the flex plates break/crack, it throws off the timing window, thus giving you an out of sync cam and crank sensor reading. I usually measure the crank and cam square wave patterns and then measure the milliseconds difference between the cam and crank. This may be to in depth, but this is one of those problems that this comes in handy and is sometimes necessary.

 

Here is a diagnostic tree for this and some of the possibilties.

 

P0016-CRANKSHAFT/CAMSHAFT TIMING MISALIGNMENT
