    Hey guys, I just imported a 93 Land Cruiser and Im looking to fab up a new exhaust system (cat flanges are rotted out) While looking it over to make a parts list I noticed what looks to be two egt sensors after the cats but cant find any info or replacement parts. They appear to be a two bolt style similar to the o2 sensors and are in pretty bad shape. I dont think i'll be able to salvage them if removed. Does anyone know if they are a jdm only sensor?

    What engine? The 1fz-Fe 93 has both O2’s behind the cats. That’s it.

    What market was your rig originally built for? Makes a difference for assorted bits and pieces.

    Gee, I was thinking they were ahead of the cats.

    O2 sensors are always between the engine and the CAT this is universal

    if this is OEM use your VIN number here

    You're right they are ahead of the cats.

    the truck is Japanese market. It also has both o2 sensors in the normal location before the cats. They definitely appear to be oem sensors. I will take a picture and post it shortly thanks for all the input so far

    Are you sure it isn't/wasn't for an aftermarket gauge? I can't think of any place an EGT sensor would go. No place on the dash for it and no need in the ECU.

    definitely not aftermarket and now that you say that I believe I saw what i believe to be an exhaust temp warning light in the cluster. I will check later today and send pictures

    Hmmm I guess it could be a cat clogged type of warning?? No idea, that is a new one to me.

    Have seen those on other early Toyotas, but never on an '80, must be a Japan thing? What happens when they are unplugged?

    Wrong! US market OBD II rigs have one in front of and one behind the cats.
