Does meth injection kills o2 sensor

[Absolut1M]

Hi all,

I am a newbie and I am running cobb custom map by PTF with catless dp and recently installed AEM meth injection running 50/50 mix, running around to test if everything works but before I could log and tune I got a code for dead o2 sensor.

Question are,
1)Doesn't cobb turns o2 off so we can run catless or high flow cat?
2) does meth kills the o2 sensor easily?

1) Cobb maps will suppress the secondary O2 sensor codes for running with catless DP's, what codes are you getting?

2) No, shouldn't kill the O2
