Best case you can find a used TPS from another Supra that you can use as a test. Also, check the harness with a multimeter.
I had a problem with my TPS once because some moisture got into it.
All these troubleshooting steps are in the TSRM - you need to get one because the Mkiv Supra is too rare for your local dealership to keep one on the shelf.
