I have a 2002 accent, which i brought brand new. The car currently has 108k. I have always gotten the suggested maintenance done, including oil changes.
My current issue is a recent check engine light. Auto Zone gave me a code of P0133. Which, from my research could (hopefully) mean only an 02 sensor. The light just came on last night, however the car seems to be running as normal.
How concerned should I be about this? My car is not due for state inspection/emissions for another year. Can I wait that long? Will there be damage? I would like to own this car another 3 years and her to 140k, without any major investment (Question part 2-do you think I can drive her that long, what are your experiences with this car?)

 

0133 is typically result of exhaust leak at flex section of the front pipe.

TSB issued 5yr ago telling how to remedy to exhaust noise/0133 concern

 

would i be able to hear an exhaust leak? Would a mechanic be able to tell the difference between a sensor problem and an exhaust leak just by looking?

 

I am taking it in tomorrow. A local place and not a dealership. Any idea how much it could run?

 

Co-worker just replaced 1 this morning,, while GDS is installed for code work, may as well upgrade the PCM with #52 for an Ox logic (0130 logic) and hit the TCM to bring it up to date also.

 

I posted the TSB at the other site where you asked about 0133.. I can upload it there, the file was too big to put up here..

Thanks that was the problem. Not if I could only figure out why my belts are making some noise upon start up.
