Drivable short-term, but fix now to avoid damage.
P0016 means the computer sees a mismatch between the crankshaft and camshaft position signals. This can come from a stretched timing chain, a faulty VVT component, sensor problems, or a jumped timing belt. Because it can point to serious internal timing issues, it deserves prompt attention.
$150 – $1500
Varies by vehicle and root cause.

It varies widely, from about $150 for a sensor up to $1,500 or more if a timing chain, guides, and tensioner need replacing.
Yes, it's one of the more serious timing codes. Because it can involve the timing chain or belt, it should be diagnosed promptly.
If the crank and cam are far enough out of sync, the computer can't time fuel and spark correctly, which may prevent the engine from starting.
