I'm trying to purchase new O2 Sensors. All four.
I find every different number and description in the world out there on these things. Heated downstream upstream 4100 banks 1 and 2 whatever.
For an 01 F150 Lariat Super-crew 5.4L 2WD 4R70W Trans - There must be some definitive answer as to what parts I buy?
Went to Rock-Auto and became VERY confused, Auto zone is all over the map. Everyplace I go they use different terms.
Anyone know for sure, I'm guessing enough as it is.
First off, no one EVER needs all four sensors unless they have money to just pi$$ away. You might want to back up and redefine your actual needs so you don't waste time and money replacing parts that are either still serviceable or aren't going to fix whatever you think they will.
The two upstream sensors are identical to each other.
The two downstream sensors are identical to each other.

I don't need to backup or redefine anything!
I am replacing the O2 Sensors - Period.
Thanks for your help though.
