P2270 with Vibrant J fitting

[Anthony]

'13 RS: anaconda, ZZP cat back, MPFab intake, full tune.

I keep getting a p2270 code. It's reading lean at the O2 sensor. I got the j fitting to prevent a CEL but I'm still getting one. Any ideas?

You did put the fitting in the 2nd O2 bung right? Just want to make sure it's set up correctly.

Other than that, which J fitting did you get? There are at least 2 sizes, maybe if you got the shorter one the sensor is not removed enough from the exhaust to read clean.

Pretty much what Dubbs said, make sure its on the 2nd o2 sensor (farthest away from motor) I bought this one and have yet to get a CEL http://www.amazon.com/gp/product/B002U70614/ref=pd_lpo_sbs_dp_ss_3?pf_rd_p=1535523722&pf_rd_s=lpo-top-stripe-1&pf_rd_t=201&pf_rd_i=B00AQ7972O&pf_rd_m=ATVPDKIKX0DER&pf_rd_r=1W21DD6STNFGAK6841ED

If you're using trifecta, turn the rear O2 codes off in the tune program (EZ Flash?) before you flash the tune.

If you're using another tuner (VTuners or HPTuners/EFILive), have them send you an updated tune or turn the appropriate codes off in the DTC section.

Using the J-fitting should allow you to not have to do this. I have been running a J-fitting for about 10k miles with no issues.

This is exactly the fitting I ordered. Going to check with my mechanic on everything else.

Just pop the hood of your car. Is the J-fitting visible next to the turbo in the downpipe? (It would be right there... extremely visible).

If it's not there then it should be in the right hole.

Yep I know, it's a band-aid to turning the codes off. If you're tuned, there's no reason to have one.


Anthony, I'd check under the car to see if the J-fitting is down there. Perhaps it was installed in the wrong O2 bung? Should be installed in the downstream (post-cat) bung.

Nope not there.

okay. then my guess is gonna be that it was put in the right hole.
