TPS voltage -- where does it come from? Trying to trace the wiring
Hey guys,
Car is 84 T/A with CC Qjet. I'm trying to find the source of the voltage of the TPS (Throttle position sensor). The TPS is supposed to get 5V...does anyone know from where? I'm getting 5.9v and i am wondering if I lost a ground somewhere that draws it down or if I'm shorting to a wire that might be conducting that extra .9 volts. Any thoughts of ideas would be greatly appreciated.
