call a parts store, and ask for two...when he says HEY MORON THERES ONLY ONE(we love parts guys) then you'll know...but
Everyone should have a manual for their vehicle, and the local library should have a professional shop manual available to make copies of for FREE...make the time to take time to read up on your vehicle, and work like the PRO'S! Good luck :)
I'm not quite sure what the above post is getting at, but it seems to me he's saying there is only 1 O2 sensor. There are in fact 2 oxygen sensors, an "upstream" sensor and a "downstream" sensor. The upstream sensor is located on the exhaust manifold on the passenger side, if you look down from the top of your engine you can see it near the botton of the manifold. The downstream sensor is located just just after the catalytic converter (which is underneath the truck pretty much in the middle)
