Okay heres the dealio.
I got my motor back into my 00' GTP, got it fired up and sounds good.
Heres my problem i cant figure out
Its throwing a P0122 engine code, TPS circuit voltage low or something along those lines.
Car wont shift correctly, shift at 4k and havnt gotten it out of 2nd (not registered till emissions can be done)
Idles high then it should
I did try swapping TPS sensor with a parts car i have, same deal.
I did some testing and found out, the power signal to the TPS is 5v like it should be, the ground had 11-12V. Heres where im seeing a problem the middle wire on the tps connector, should real .5v or around there with the throttle closed and the reading on my VDC meter should go up as i slowly open up the throttle, and should go down as i close it. Well...
When i probe the middle with with power lead to my multimeter and gound the black lead to battery im getting .17V AND when I open throttle i get no change in the reading??? Whats going on?
I did my testing according to this website

Any suggestions on where to go from here?
