yesterday after waiting for two weeks for getting a new rear O2 senor i put my test pipe on. went for a drive and really love the sound with invidia v3 cat back and now invidia 70mm text pipe with cel fix but it is loud. well after about 15 miles the cel light went on, so i had the codes read and its all the secondary 02 sensor. i dont want to look at the cel thats why i got the one with the fix on it. so what do i need to do for it to go out and say out. right now i have rest the ecu for it to go out but havnt driven it. any advice or help would be great.

 

i stacked 2 anti foulers and a cel fix on my 08 and i scanned the ecu with no codes for the o2 sensor, try putting some anti foulers on it

 

Read my thread a few down... I did the exact thing.. even put on 3 nonfoulers... still a cell...

Have it fixed for the time being.

 

Get the Code....


It's in the FAQ: https://www.s2ki.com/forums/index.php?showtopic=378792

 

i had the codes read, they were p0136, p0138, and p0140

 

but it seams i need to get the 02 sensor farther out of the air flow with the anti foulers???

 

Did you replace the 02 sensor with a new OEM one or an aftermarket sensor?

 

got a new OEM one, but advance got in two for me, so i may change it out for the other one just to make sure its not a bad one.

 

just add more spark plug anti-foulers and reset the ecu.

 

I had used two anti-foulers and code would pop on every few days. then i removed the crank case breathers from the intake manifold and intake and the check engine light never came back on.
