What is the level of fluid in the power steering (PS) system
reservoir?

Do you see any PS fluid on the ground beneath the car, or
other evidence of PS fluid leaks?

Candidates:
If non-Honda (PS) fluid was added to the system at some
point, certain steering components are being destroyed by
it.

With luck someone simply had the PS fluid system open (e.g.
for a timing belt job, the PS pump is in the way and has to
be removed on some/all Hondas) recently. Or the PS fluid got
low for some reason. Then the problem may be just air in the
system. Buy some genuine Honda PS fluid (available at
Autozone or similar places; it will say something like "For
Hondas only" on it). To purge the air: With everything back
together, and the power steering reservoir full, take the
steering wheel and turn it back and forth 50 times.  With
the power steering reservoir full, get a friend to standy by
with a bottle of power steering fluid as you start the car.
When you start the car, the pump will suck down all the
liquid in the reservoir into the system.  It is CRITICAL
that the pump not suck air into the system. Start the car
for 1 second and shut it off.  As the level goes down have
your friend add to the reservoir.  Repeat as needed until
the reservoir level is filled appropriately.  When done,
replace the reservoir cap, start the car, and twist the
steering wheel and listen for "squealing".  As long as none
is heard, you're fine.  Again, it's important to keep air
out of the system.
