hey
ill make it short and sweet, unless im mistaken its a bad tps not everything new is good. If your old one is seeing the same voltage then you should be looking elsewhere for a problem, ecu and wiring including grounds.
hope i helped out

Have you checked to make sure the throttle blade is opening all the way? What was the reason for the replacement?

also make sure (as eluded to) that you have 5.0 volts (+-0.1) and a good consistent ground signal.

Check the Orange/white wire for +5 volts +/- .25 volt. If it is OK, then replace the TPS.

No +5 volts on the Orange/white wire, look for bad connections.

Check the Orange/white wire at the EGR & MAP/BAP, no +5 volts, check pin 26 on the computer. No +5 volts there, computer is bad. If the +5 volts is OK on pin 26, then you get to chase through the wiring harness to find the bad wire/bad connection.
