My guess is that is the engine code your getting and you are wondering what it means. Ussually it means that you have a bad oxygen sensor. It is the oxygen sensor that is downstream from your #1 cylinder. To know which cylinder is #1, you have to find out what engine you have and compare that to a firing order chart. Any Chilton's or Haynes' manual for that vehicle will have one.

I've read that this code might be a downstream O2 sensor. Possibly on the passenger side and pre-catalytic converter.

Where is the downstream heated oxygen sensor heater circuit fault bank for a 1996 ford f-150 in line six cyindler?
There is no such thing as a "circuit fault bank." That was the terminology your scan tool used to tell you that there is a fault in the downstream heated oxygen sensor circuit. There are three sensors screwed directly into the exaust system. Two you will see under the hood, screwed into exaust manifolds. Those are the upstream oxygen sensors. Now get under the truck. Find the lone sensor that looks like the other two, screwed into the exaust sytem after the catalytic converter. That is the downstream oxygen sensor. The downstream oxygen sensor circuit that there is a fault in, includes that sensor, and all the wiring in that circuit all the way back to the PCM (computer), and includes the PCM itself.
