Yours should have three if memory serves me correct. Two up streams, one in front if the left cat and one in front of the right cat. Then one rear down stream behind the third cat.

I believe Denso is made/makes Dodge's o2 sensors.

thanks. i have looked at a few parts sites and they seem to say there are 4 sensors, 2 on each site upper and lower. Is that right?

I would just crawl underneath and look, there is at least one after the cat and possibly one or two in before the cat in the pipes before they connect

there are 4. i don't know how you get at the top passenger side, though.
