    O2 sensors

    While I know that O2 sensors are designed for high temps (exhaust heat), can you ruin them by over heating, say with a torch? Like torching exhaust bolts and flanges very close to them?

    I run my Exhaust temperature pre turbo at around 1800° with a narrow band and the wide band about 3 feet down stream. Headers glowing red at the 1/4 mark.
    I would say you are not going to hurt anything even if you hit the 02 sensor with a rosebud torch.

    Typically if the wideband sensor is too close to a heat source it just won't read correctly until it is moved away from the excessive heat source

    You will be fine

    Yes, I wrecked one heating the manifold to remove the studs for the cat pipe.

    So one answer says it won't hurt them, one says it could. Kirk I would suggest if they aren't to expensive have a set handy,if you don't end up needing them return them or keep them handy till the ones you have crap out.

    Update from today, harsh vibration can kill them. Don't drop it, don't use impact tools. Shop used an air chisel also.

    Can't say for sure yet. May all be a coincidence.

    Long story short, took the Montego to the shop for exhaust work. No codes before it went in. B1 S2, and B2 S1 O2 codes after. Owner says it can't be them. Replaced B1 S2 (inches from the flange they worked on) and all clear for a test drive. It was them!

    Drive it tonight and the light came back on. Not so fast, is this B2 S1?

    I'll check it tomorrow.
