if its in the front change that MOFO...quick... I had that same thing happen...and it caused a bad miss fire eventually...

just replace it... you can get one from AutoZone, Pepboys or Advanced AutoParts... for like $70... or less...

alright . . . do they flex shut do to heat or something?

I'd say try cleaning it... if it doesn't work...replace it... it's not that expensive and you can seriously do it yourself...

yeah ive changed O2s they are easy I just wondered if this was a common thing when the computer reads this kind of error that it usually means the O2 needs changed or if something else could cause this

i think i fixed it. i took the front drivers side 02 sensor off, cleaned it, and spread the "gills" out a little. i reset the pcm but the ses didnt go off. however today the ses hasnt been on all day.
