Best Answer

My SR-5 has only one oxy sensor. It is located just forward of the Cat converter on the exhaust system. It has two metric nuts holding it in place The Bosch oxy sensor was $100 or so... At the same time I replaced my Cat converter and Muffler. The Cat had over-heated several times and ruined all of that stuff all in all pretty easy fix!
