the m16a is stroked M15a. they are sister engines. the vvt valve even has screens (rumors) that clog, with zero or poor oil service.
see that wire there, a very careful examination is warranted, as is re-seating it,
A shop many look at the chain and go, chain ok, then replace the valve. and the magic sprocket and tension-er all in one go (called the shot gun fix)
or do this is 3 very trips to the shop. easy to harder, (labor will dictate order)
good luck with VVT, it is hard to diagnose device. ( after all how can you watch it running, if you could use spark timing light to see if the advance retard works.
