CEL help.... (stg 2 93 bm3 v7.1 FBO ewg n55)

phat8186 · 03-03-2020, 09:09 PM

Finally updated to version 7.1 EWG N55 FBO, I was sitting pretty at version 6.4 with no issues ever.
I've never had a CEL for my catless DP before since bm3 suppressed it. I hate seeing a CEL and I cant get it suppressed again.
Any insight would be greatly appreciated, or guidance to situate this little problem

The code in question:
12B304 lambda probe heating after catalyst activation : line break

Cat monitoring set to Off

Stage 2 93 v7.1 FBO EWG N55

I have on there Facebook group but was told
" Halim Cazimi Code says line break, O2 sensor wire damaged maybe. "

I don't get how the wire could be damaged if my car was up in the air since November on my lift

Literally turned her over the other day to prep for spring and I had this code. I put her away nice y nice and she wakes up with a code not cool.

For real I'd be pretty tight if a mouse did this. That means the little shit climbed up 72" onto my lift to nibble on my o2 sensor

Guess I got some exploring to do this weekend till then back up in the air she goes.

I also had a mouse chew through wire loom and 4 wires on my 3000gt - had to repair/solder the harness back together. It happens more often in winter, especially when cars sit for a while.

This is the first time this has happened she always sits in the air for the winter.
Good looks on the insight people.

I will report back once I have looked at my o2 wires.

Did you get to find out what was wrong?

The OP's particular code was for the rear O2 sensor. I had the exact same code and replacing the secondary oxygen sensor remedied my problem as well.

Insane435 · 11-19-2021, 09:09 AM

I just had the same code pop up. Did you guys replace the sensor from the top?

I can get my hand on it pretty easily. I assume with an o2 sensor tool and extension bar it can come off.

the rear can be done from the top I believe.. easier to do top and bottom.

So I can get the socket on the o2 sensor. However, i cant get any leverage to loosen it. If i put a long extension on the socket it becomes such a weird angle that there is no way it will turn the socket. Going to have to get it on a lift.
