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?

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

Looks like a factory cat temp warning light. Does anyone know if these send a signal to the ecu or just the cluster. I wouldn’t mind bypassing them with a resistor if possible

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