Yes it has 2 separate sensors, one for the AFR and one for the guage, I actually have both of them (spares) brand new if you want to try the one out? Also just let the car warm up then check to see what loop you are in, did you mean your scanner does or doesn’t read that? If not mine does, if you need a hand let me know and I can swing over tonight, as long as you dont live terrible far away!
