Gen 2 heated 02 incomplete
Looking for some advice. I purchased a 2002 gts years ago. I have to smog for my state emissions test. The heated o2 sensor reads incomplete. The rear oxygen sensors were replaced with dummy sensors by a previous owner. So no issues with check engine lights etc. today I replaced the rear dummies for correct o2 sensors. I guess my question is, why would someone replace the rear sensors with fakes? Iím hoping after I drive it tomorrow Iíll be ok but Iím almost certain that wonít be the case. Please advise if at all possible. Thank you all very much.
