RZtwin Posted August 3, 2020 Share Posted August 3, 2020 Hello, I have a 93 JDM Supra 2jzgte. I have installed a Haltech 2500 and I am in process of installing a PHR single turbo kit. Just wondering if I can unplug the cat temp sensor? Will it make the car run abnormally or leave a dash warning light on? Thanks! Quote Link to comment Share on other sites More sharing options...
AC93 Posted August 4, 2020 Share Posted August 4, 2020 You'll be fine unplugging it. I unplugged mine when I went BPU with a full zaust system and I had no lights or anything Quote Link to comment Share on other sites More sharing options...
RZtwin Posted January 15, 2021 Author Share Posted January 15, 2021 Could I delete this sensor and wire all together without any negative effects? Quote Link to comment Share on other sites More sharing options...
shaky Posted January 15, 2021 Share Posted January 15, 2021 Just take it off ? or tuck it up and seal off at the end , use a tie back, mine is BPU , it's ready to go back to stock if needed . Quote Link to comment Share on other sites More sharing options...

Its purely there as a safety feature. To let the ECU know if your engine is running too lean, too hot so it can make changes to the fuel/air ratio to cool the gasses down, As with all sensors, you only need them to tell you or the ECU there is a problem, remove this and your ECU will never know if there is a problem. The good side is over temp on exhaust gasses tends to be more of an issue in smaller high compression ratio engines than old big lumps like the 2JZ with its massive oversupply of oil and water flow/cooling galleries.
