TPS troubleshooting

Does anyone have information on the correct voltage values expected from the TPS? Mine, (2005 FLH), shows .380 at idle and 2.8 at WOT. SmartlinkIV thinks this is only 10 idle and 32 degrees WOT (obviously WOT should be closer to 90 degrees). What voltage should WOT be? Me thinks closer to 5.0 volts.

TPS and volts

On the DTT the Idle volts is approximately .4 volts; 50% is about 2.0 volts and 100% is 5.0 volts. I am sure the Delphi is close since they use the same Throttle body and sensor.

Don't know the exact closed throttle tps volt specs for your bike but every tps I've worked with has a range of approx .5 to 4.5 Volts.

Thanks. I found with a good EFI, the voltage is indeed .5 to 4.5 volts. Obviously I have a defective EFI as it pulls the voltage low. Mystery solved.
