Hey everybody ....Got a Check Engine light on 97' Dodge Dakota v6 3.9L ..I guessed it's oxygen sensor, and today, my wife found some free diagnostics somewhere and the guys there said it is ...As far as I can see it's only one O2 sensor after the catalist, but on auto part sites, when searching for the part they always show FRONT and REAR items ...So can anybody tell me how many O2 sensors goes for this model and if one, will it be the REAR one ...?
Thanks in advance ...

 

You have 2, one after the cat and one in the right side headpipe up near the frame rail right after the manifold.

 

I have a 96 v6magnum, does this aplly to that model too?
