Funny TPS readings ...

Easiest way I know, is to slot the little screw holes in the TPS, so it can be rotated like an earlier year model adjustable TPS.
I have not had one fail to show 100% Throttle Angle, if the Throttle Body is opening all the way, against the stop. Don’t buy your sensors at Autozone. Use genuine AC Delco, or NAPA.

Most newer EFI systems have a TPS calibration procedure in them. Heck, my old Haltech I used to run back in the early 90's had a way to calibrate the sensor.
