Mont Posted August 18, 2018 Share Posted August 18, 2018 I just got my Supra up on a ramp for the first time since owning it and discovered that the first cat is looking a bit worse for wear, so this is perhaps the push I need to go BPU and replace it with a decat pipe. The thing is, I'm unsure what this sensor is in the pic below. It's been put in post cat and looks to have been bodged in with exhaust paste which fell off it when I start prodding it. Is it an EGT probe? Whatever it is, is it OEM to the car, or is it something aftermarket? The wiring goes up in to the car over by the drivers side but I haven't been able to figure out yet where it goes after that. The car is a 1995 JDM twin turbo. Thanks Oh and just whilst I'm posting this, I've just bought an AEM EGR/Boost gauge. If I buy a 2nd decat, do I just need a decat with a single boss for the O2 sensor?

Al Massey Posted August 18, 2018 Share Posted August 18, 2018 It’s the CAT temp sensor Most/all people just tie wrap it up and leave it out when upgrading. Quote Link to comment Share on other sites More sharing options...

pedrosixfour Posted August 18, 2018 Share Posted August 18, 2018 Wiring continues in through the floor on the driver's side. There is a connector under the carpet. Quote Link to comment Share on other sites More sharing options...
