Oxygen sensor low voltage
Quick question. I just installed ARH long tubes on my 14. They are used and the rear sensor holes are still plugged. I knew I would get a CEL for that until I got it tuned. I am also getting low voltage on both front sensors. Is this because the ARH moves the front sensors back a
bit and the computer on the stock tune still thinks they are in the oem location? I’ve got a tune appointment this week but didn’t want to waste the tuners time if there was an issue tuning won’t solve.
thanks

No , you should not get a Low voltage CELfrom the fronts just because you installed the headers , they are farther back and the tune will handle that . Are you sure it's the front sensors.... and not the rears because they are not plugged in ?

Duh I’m an idiot. All codes say sensor 2. Which since they are gone makes perfecto sense. I had to go back and scan again. That’s what’s I get for doing critical thinking stuff late at night.
low voltage bank 1 sensor 2. Bank 2 sensor 2. Heated o2 circuit bank 1 and 2 sensor 2. Time to put the wrench away for a bit until I get my head out of my *** it seems.

It's all good lol we have all done it , as soon as I saw the "low voltage " I figured it was the rear sensors
Good luck with the tune
