OK, so I literally have 12 miles left on my 36k mile bumper to bumper warranty. Last night it threw a P0133...the first time my check engine light has EVER been on. I cleared it and it never came back...the Jeep Dealership is about 8 miles down the road...should I have them check it out anyway? I know it's just the O2 sensor but hey, if I can get a free one out of the deal before the warranty runs out, then I'm going to take it....any ideas??
