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.

Symptoms of a bad knock sensor?

There are no symptoms since the knock sensor doesn't do anything unless the engine is detonating, in which case it would do nothing and you would hear it.

Why is the engine light on in your Ford Fiesta?

The engine light comes on to show that there is a fault. Usually it is caused by a faulty sensor. You would need to have a diagnosis done of the Engine Management Unit to find out what the fault is. Taking your car to the dealer will cost between £60-£80 but you can buy a diagnostic tool quite cheaply from Ebay or Amazon which will give you a fault code telling what the fault is, if it is a minor fault you can reset it and the engine light will go out.
