I have a 94 Rodeo 3.2 throwing a code 13. I have purchased a replacement O2 sensor, but for the life of me I can't find where it goes! I've read it screws into the exhaust manifold, but I have looked as hard as I can from above and below, and don't see it. Is it hidden?

Any tips for finding it would be greatly appreciated. :-)

 

Try looking on the exhaust pipe just after where the Y piece joins together where it becomes a single exhaust system.
