I have a 2005 rsx-s and have purchased dc race headers for it... Check engine light came on which I knew it was going to happen so I ordered an O2 simulator for it and still wouldn't work... It's throwing the code P0139... How can I fix this problem without reprograming my ecu...

 

I don't know, I haven't tried it myself yet! But I would personally wait to see if it will fix itself; if not, reset the ecu and see if the codes comes back on!

 

yeah thanx... I've tried that several times... It seems to be a perminant light, I've read about kpro but they don't have it for the 05's yet unless if I get 02-04 computer...

 

I would try and search, because I think I read somewhere that O2 simulators wont work on the 05-06.

 

yeah... you know there's really nothing I can do as of right now... I'm just thinking about replacing my dc race headers with the dc regular headers. I know it sucks to do that but I just hate looking at that c.e.l. And when kpro does come out with 05-06 program then I'll put the race headers back in... What do you guys think...
