Bank 1 Sensor 1 Code

DYOOS · 05-22-2019, 07:07 PM

I've returned my car back to stock. I've also recently removed xHP and flashed MHD to map 0 (will remove MHD completely once I get my car back from the shop).

The shop said my Bank 1 Sensor 1 is not registering. Could easily just replace it, but I'm wondering if this code is popping up because I just turned the car back to stock, MHD is still installed on map 0 and I haven't driven the car for 100 miles since? Or would I need to just replace it? I've read that the car needs to adjust itself then the code will go away.

Fixed this issue. Just installed a new oxygen sensor for bank 1 sensor 1 (cylinders 1-3).
