Best way to reset after O2 install...
I'm about to replace both of my sensors on my 99 taco 2.7 and I've read the different ways to reset. I'm curious from experience if one way is quicker/safer than the other. Options are either pulling the neg cable on the battery or pulling the fuse... I know you don't have to do either the computer will eventually adjust but when I do it I'm not sure I want to let it just run it's path as I think the O2 sensors have not been working properly for a while.

Man what are the odds! Im actually doing this same thing on mine right now. Mine is a 3.4l but still a 99. Im concerned that the replacement I got at Advance doesnt have a long enough pigtail on it. where did you get yours?
Not sure on resetting. Intrested to see the answers though.

If your going to keep your truck a while and do allot of your own repairs and troubleshooting just get one of the cheap $50.00 code scanners / Code erasers and keep it in the glove box.

Its nice to be able to read the code and find out what that check engine light is telling you ASAP.

The only time I have intended to reset the ECU was when I had the dash apart and the ECU unplugged anyway. So I was not sure if the ECU would reset with the batt or not. Seems like it would have some type of backup so it doesnt reset everytime the batt dies.

Agreed...but Im not sure what that has to do with resetting the ECU.

Yea my half awake brain just saw that reset after O2 senser and it made me think resetting the check engine light. I have a rear O2 senser that ever 3K miles throws a code about the catalytic converter threshold being below limits and his post about the senser made think of that.

I bought Denso replacements off of amazon and they have pretty close if not exact as stock. It was between that or Bosch but I did some reading and glad I went with what I did.
They were $146 for the pair. I got the info for the Denso replacements at

Ha yeah I am getting great info from your thread... I just don't think they have a supercharger for a 2.7. Even if they did my financial status wouldn't allow me to purchase one atm.
So I was all paranoid how I was going to get those half disintegrated nuts off of the studs for the rear O2, well on the concept of putting a bunch of heat into them and then going for it, i figured my exhaust would get a bit hotter than my butane torch could get them...so I drove around for a while and then jumped under there (with some leather gloves on of course) and a pair of vice grips.
Needless to say they came right off!!

So although it isn't the same length the verdict was that they worked...I believe it was more about the life of the two (denso vs bosch)
Never mind disregard this. you are talking the wiring, I was thinking the sensor sticking into the pipe. NVM.
But there was a company that had a shorter sensor...how long is yours compared to stock?

Man thats ballsy! Did you try and remove them without heat? Mine came out pretty easy with a long handle ratchet. I had to use the flex head to fit in there but it worked pretty well. I dont think I waould want to be under a hot truck like that!

one wonders why you are replacing both the o2 sensors? separate codes will list bank 1 or 2...
the easiest way to clear codes is to pull the EFI fuse for 20 seconds (under hood ) saves resetting the clock and radio presets and the alarm noise too.
