    Anybody experience this? I just replaced this sensor about 5 months ago. Could it have gone into trouble again from the new Magnaflow muffler's fumes burning off or something?:confused:
    Thanks.

    what brand did you replace it with? that does matter, since some are shit. try unplugging battery overnight and see if it clears. or deal with it until the truck cycles 2 successful trips over a certain milage to clear it by itself.

    My bad, I forgot that I sent this back (because of the missing flange) and I got the right sensor from Advance Auto Parts

    idk about where you are, but here advance auto parts sells shit. id go to like napa or bond and get the moog o2 sensor. just my two cents, but like i said try resetting the computer via unplugging the battery first.

    Actually it was AutoZone. I've already reset it with my code reader. I'll drive it some more and see how it goes. I'm in Maryland getting ready for the frankenstorm!

    Magnaflow exhaust. Custom leather Katskinz. Fujita CIA. Custom canopy. Armourthane sprayed bed. Grey wire mod. Black American eagle wheels. Dick Cepeks FCII's. Black Emblems all around. TRD oil cap. Ignition Light Ring Mod. Blue LED dash and controls.
    Old thread but..I have had this P0136 code since the day I installed the magnaflow cat back exhaust in 2008. I have done everything. Cleaned the MAF. Looked for vacuum leak. looked for exhaust leak. Uninstalled and reinstalled the thing... Even replaced the front and rear sensors twice and it still came back every time. I then bought that sensor simulator from URD and the F$#%ING thing still came back.....I just gave up and live with it. I eventually will go back to oem on day. I read something over at customtacos.com that seemed to be an issue with this particular brand or something. Maybe its because I have the California emission setup and its more touchy if anything is altered. I dunno. Anyways good luck with your magnaflow....it sounds nice and you will loose 2-4 miles per gallon. Not worth it IMO.
