Is there more than one oxygen sensor on a 93 ford f150 5.0L engine?

Question

and where are they located?

Answer 1

im not positive but there should be 2 unless it came with dual exhaust then there should be three or four if you have a single exhaust ull have one on the manifold and one after the catayitic converter... if u have dual it should have one on each manifold and one after each catalytic converter

Answer 2

Should only have 1

Answer 3

It has one oxygen sensor, it is located in a small crossover pipe that is welded between the 2 exhaust head pipes just before the first catalytic converter.  Look under the truck on the passenger side between the frame and the transmission, it is really close to the starter.
