i have been tring ot fix this problem for a while and have not been sucessful. checked all the grounds and they are good and i have 12 volts at the tps and a ground. put a new gm tps on and it did nothing. i have a p0122 tp or app sensor 1 circuit sjort/low, p0200 injector circuit problem, and a p1122 tp circuit intermitent low voltage. I am totally stumped on this one. did all the test in the book for each code and still nothing. almost ready to swap harness's bc it seem like something is gournding out or loosing ground and causing this. the car sit alot but is in perfect shape and garage kept. The air pump will come on and off while its runing and i checked the scanner and its going in an out of closed loop.
