O2 sensors

[no name]

Hopefully someone can answer this for me. I had the cel come on. Had someone scan it real quick just to make sure it wasn't anything real major. He said it came back as a low voltage (?) on the o2 sensor. My question is can I have him scan it again to see which o2 sensor it is or do I have to replace all three of them?

Turn your key to off-on position 3 times and the 4 digit code will come-up on the odometer/dash light and hopefully it will give you the number which will tell you which O2 it is. Not sure if it will break it down for you like that but you can look it up easy. my 03 only has 2 of them, one upstream and one down.

It should have a description along with the code that'll say "Bank one sensor one" or something like that. Not sure which side bank one or two is but sensor one is the upstream sensor before the cat, and sensor two is the downstream after the cat
