Nissan 370Z Forum - View Single Post - ADMIN Tuned ECUTEK. Are o2 sensors disabled?

rogerdodger · 09-26-2021, 01:01 PM

Guys,
I have a 2012 370z Sport with the Admin Tune via ECUTEK. I have to get the vehicle emissions done so I switched the TUNE to the 'ECONOMY' mode.
Went to get the emissions done and it failed due to the o2 sensors showing not ready.

I did some more investigating and checked the Data logging via the mobile ECUTEK app and it looks like its getting a reading from the sensors as well as both o2 Heaters are showing READY. I have every other parameter showing ready except the 'o2 sensors' themselves !! I have driven the car over 150 miles and did the drive cycle via the web for this model and still the 02 sensors are not showing READY. Battery shows 15 volts as well and is only 3 years old.
o2 sensors throw no code and definitely gives a reading in ECUTEK

My Question is:
1. Does anyone know if ADMINTUNING disables the downstream sensors ?
2. Is there any way to switch them back on somehow outside of having a TUNER do this?

Looking to see if anyone else has ran into this in an Emissions Testing state?

Thanks
