I had to replace mine, as I was getting that code also shortly after I installed headers. Replaced the upstream sensor, and yeah, it should be around $75-$90 for a reputable one. If the code comes back, it's likely that it just needs replaced. Not a big project either, just do it when the engine is cold.
