Tundra O2 sensor problem

[jimwest]

I have a 01 Tundra - auto, v8, 2wd with a ck. Eng. light on.
Computer reads O2 sensor problem, but does not indicate which one.
Has anyone solved this problem without replacing all 4 sensors which cost close to $500?

Anytime that I've had an O2 go out, I just replaced one at a time, the problem is that you have to run it through a couple of cycles and keep checking the codes to see if it goes away ...

the computer should have read which bank sensor that has gone bad. where did you get the code read at? try your local auto parts store they should be able to read it for you or take it to the dealership and let them read it and find out which one it is and replace it yourself.
