    I have a 1992 F150 with a straight six.(I know sweet truck right! ) Anyway I was wondering how many O2 sensors there are and where they are located. I found the one on the exhaust right before the cat.
    Thanks in advance!

    That should be the only one.

    There may also be one on the front and back exhaust manifolds. So total you would have three. My 1996 has 3 so maybe it just depends on the year.

    1996 it was mandatory to have up and downstream sensors… but they had until 99 to implement across all lines… 92, he should just have the one before the cat
