The flowchart is helpful. If that's the only code, then check the air
filter and in the intake for obstructions. Also check the striped hose
from the pressure regulator to the throttle body.

If that's not it, the next step is to check the oxygen sensor, and I
haven't yet had the pleasure.

Check your hoses between the air flow sensor and the throttle body. If
there are no leaks, you probably need a new air flow sensor. Hyundai has
a tsb on this issue. Go to www.hmaservice.com, select webtech, select the
TSB tab, enter your vehicle information and select 36-Engine Electrical.
The TSB number is 01-36-013.
