I checked the code and it says it's bank 2 sensor 2 and I changed it out but the check engine light is still on. I have the 97 5.4 2wd. My buddy went to uti and told me that that's the passenger side downstream. But when I look it up the web doesn't say anything about bank 2 sensor 2. (Or I haven't found anything yet) but on another forum it says bank 2 is the drivers side? Anyone know which one it is?

 

What is the specific code?

 

It's po161 heated O2 bank 2 sensor 2

 

.....

 

I didn't do the right one. So can I just put the old one in and change the next one?

 

It's the driver side rear one, fyi.

 

So I looked at it and sure as ****



I left the new one in the one I changed out, and I put the old one in that's spot. Hopefully it works. I disconnected my battery to turn the code off. I'll let you know if it comes back on

 

Well there's your problem. Lol. Thanks for the update.

 

So I put my old O2 sensor in the place of that one and it still hasn't fixed the problem, now more codes are popping up, saying I'm running too lean in bank 1 and bank 2. My truck was programmed so I thought maybe it was just that. But I've set it back to stock and the same things are popping up. It's making me wanna sell the mother ****er more one day at a time lol.

 

You don't have a problem with your oxygen sensors then. Look elsewhere. Search your codes on Google.
