Kill those O2 sensor Codes!!

These sensors clearly made a difference because I replaced them one at a time and checked the OBDII and the code for each disappeared as I changed them. It smoothed out the running of the engine. The only thing that could have gone easier is if the right bank sensor could have come out as easily as the left bank sensor. But, 1A Auto isn't responsible for seized sensors. That's where your DIY experience comes in!!

These sensors will fit on either the downstream or upstream position depending on the vehicle you are purchasing for. Please be sure to match all of the specifications in the listing with your vehicle prior to ordering.
