I have a kitchen faucet whose surface consists of a base metal ring,
a body sleeve, and a metal handle. At first glance it appears all
metal parts are in contact with each other. Measurements reveal the
base metal ring is grounded (measured 0 volts AC and several ohms to
a grounded receptacle's ground pin), but the sleeve and handle are
not grounded.
Is there any code violation here? This faucet is 20 years old. I
don't mind replacing the faucet if it helps.

It is normal. Do NOT count on plumbing as an electrical ground. Do not
use plumbing as an electrical ground. It can be damaging to the plumbing
and can be dangerous. You outlets should all be grounded themselves. All
outlets near a sink should be GFI protected.

In an old home you may not have proper modern grounding. Assuming it
was installed correctly to start with, has not been defeated by later
modifications or had some sort of failure due to accident or age, you do not
need to update except under certain conditions.
