CEL Fix, Need help with the rear o2 sensor

subiee sTi · 05-02-2010, 11:29 PM

I need help to get rid of the CEL because of my rear o2 sensor..I already have a spacer that I bought from ebay..but it does not eliminate the CEL. Does anyone have any other suggestions on how to eliminate it? If possible can anyone provide me with a link to a product if u know one?

you may need to replace the o2 sensor

Opensource tune it out. But you know your car won't learn and fueling trims, right?

What do you mean by it wont learn the fueling trims??...I thought that the rear o2 sensor doesnt even matter..if it was the front, I know I would have to replace that..but from the research I've done, the rear o2 is pretty much useless.

if you use opensource to turn the light off thats all ur doin, just turning the light off. if theres any kinda problem it will still be there. what i mean by that is say u have a misfire, u can turn off the cel for that specific code, but the mis will still be there.

fwiw i had the electrical fix on mine, my wb02 wasnt reading what the fuel targets were, i removed the resistor and the fuel targets are spot on, and for whatever reason i havent had my cel come on. and i did not use romraider to turn it off.
