Here's how I adjusted my TPS.. It is very sensitive, but easy to adjust. Once I got the special screw out I replaced mine with a hex cap screw. Hope this helps.


TPS adjustment procedure: disconnect the tps connector from the harness. set the DVM or digital volt meter for 20 k ohm
touch the red lead to the green pin and black to the center pin. it should read at edle position the dvm should read 1.45 to 1.52 if it is not loosen the torx head screw and twist it slowly until it reads correctly.. then slowly twist the throttle and observe the dvm numbers climbing until they read 4.7 to 4.88. then go back to idle and see if the numbers are back at 1.45 to 1.52. once that is all with in range put the red test lead to the center and black to the yellow pin. it should read 4.4 to 4.45 at idle then slowly twist the throttle until is at full setting , it should read 1.2 to 1.4 if the TPS is working correctly and not damaged.. it the tps is untouched from the factory it is usually set correct
