You should sign up for a free account on the Hyundai service web site. It has a wealth of information for folks who do their own work, or just simply want to know. Go out to hmaservice.com and sign up. You will need to use IE as Mozilla does not work with the site.
From the hmaservice.com web site...
***********************************************
FAILURE CONDITIONS [FOR P0133]
(FOR P0133) The ECM will set P0133 and MIL will turn on if the ECM does not sense the following conditions during two driving cycles:
1.. Over a period of 2 minutes, the ECM must sense a fuel compensation factor greater 85% or less than 95%: 2.. The ECM must make some correction in the air/fuel ratio when: a.. Engine RPM is between 1600 and 3200 RPM. Engine load range is between 1.35 and 3.4 milliseconds. Catalyst temperature is above 372C (702F). System is in closed loop.
This code indicates the engine air fuel ratio is not being adjusted by the front oxygen sensor signal or the ECM as expected to do so, or not adjusted as often as expected to do so once the engine is warmed or under normal engine use.

Also from the same site...
*********************************************
There is a TSB # 06-36-004 that deals with this code. It advises to verify the integrity of the front exhaust pipe between the front and rear oxygen sensors. A leak in the pipe can affect the ECM diagnostic logic for the front oxygen sensor.
