Fun new cat codes

P2C7F
Lambda probe after catalytic converter 2, trimming control

P2C6A
Lambda probe after catalytic converter reversed,

That's how they showed up. I assume this means my O2 sensors are bad.

Running COBB Stage 2+. SES light comes and goes.

Which bad boys (sensors) do I attack with fury tomorrow?

looks like those are related to the secondary O2 sensors... not sure which bank though

yeah, definately looks like the secondary O2 sensor. Im suprised it didn't say which bank.

I have the exact same codes running cobb stg2+ after DP install. Checked to see if sensors are installed incorrectly and they are fine. Gray on short DP, black on long. Did OP ever resolve this issue and if so what was the fix? Bad sensor? I don't have any other issues other then the light and codes.

This happened to me on the early Stage 2+ maps. They never reappeared after the next map update so I don't know what it was.

The SES light would come and go and it would trigger these codes. It's been a while so I can't remember which update it was, but I updated to the new COBB maps when they were released and it never came back after that.

Ur probably running too much e85 if ur getting them on jb4 I would assume.

Regardless. Post cat lambada sensors don't do d-ck really at all. It's the pre cat ones that matter.

i have the same problem with o2 sensor after cat,bank 2,the problem began using cobb with atr, maybe because i change the afr ?

Gugs · 07-15-2012, 08:16 PM

Is there some kind of downpipe/cat fix in the Cobb? I would turn that on to help with this.

Just out of curiosity, can you elaborate what to look up?

JLiusifer · 12-07-2014, 11:49 AM

I got the same two codes after I got my downpipes installed and tuned to Stg 2. Can anyone help?

Maziata · 01-26-2017, 12:11 AM

I know this is old, but did anyone figure it out? Currently happening with me on the stage 2 tune as well.
