tsp problem for na t supra
 

i am having a problem with my tps it is reading 100% throttle at all times a constant 5 volt. i just installed an aem ems thinking that it was the problem i put in the stock ecu in same problem. i believe that i am getting back feed somewhere because i am getting the 5 volts through the aem tps pin. the tps pin should not be getting any voltage at all. anyone else ever have this problem can anybody give any suggestions thanks
