Ohh Two! Sensors (1 Viewer)

[peneumbra2]

So my O2 sensors have to be replaced. Decided to have the Toyota dealer replace them (I'm at our Flagstaff house for a while).

Go over there at the appointed time, hang around for an hour or so, and discover that, while the boxes that came from the warehouse have the right numbers on them, the actual sensors are wrong. They ordered the correct ones, and they arrived Thursday.

Ok, so I come back today (Friday), wait around an hour or so, and the tech comes out and says that, because the exhaust system is rusted, he doesn't want to attempt to remove the old sensors for fear of the pipe just falling apart. So now, I've got the proper sensors (at a discount), but I've still got to find somebody to install them, and maybe put together a new and improved exhaust.

The guy who had the muffler shop here for about 80 years finally retired, and I'm not sure anybody else in town is doing exhausts. But I'm gonna find out...

What year? Makes a difference on easily available parts.

Why didn't the dealership tell you the first day you were in there that the exhaust is too rusty?

It could be completely recoverable and they are just too lazy to actually work on it because it will take up valuable floor space and time and they can cycle more newer cars through for less actual labor time while yours is in the way......

They just unscrew. Why not replace them yourself?

Your signature says you own a 96'model. I have a 96' and my nuts were rusted out. Our year models have a flange style o2 sensor with two studs on the exhaust flange and a flange with two holes on the o2 sensors. Mine nuts were rusted and flaking apart. I chose the vise grips out of the tool box and twisted the nuts off, chased the studs with a tap and used OEM nuts to install Bosch sensors. I can look the p/n up later.

Your truck is lifted with big tires so it'd be really easy to crawl under there to assess the situation. At the least, give that a shot for inspecting the exhaust and the O2 sensor nuts.
And then post up a photo or two.

@peneumbra2 : Post up some photos showing the old O2 sensors in place along with the bungs, studs, nuts, ---

In 2017 Toyota Japan approved a recall campaign from 1995. Replacement of two O2 sensors free of charge on my 94 rig

it my nuts didnt open they had to take the section down and warm my nuts with a torch, repace the nuts and studs with new ones that came with the kit from japan

Took it back to Toyota Flagstaff, and the techs managed to R and R the sensors without destroying the exhaust. The back two BOLTS were rusty but the pipe itself was OK.
Coulda done it myself I guess, but I'm working on my '47 Packard right now.
