Volts not changing?

[bcjjones]

Trying to adjust my TPS but it seems like the voltage doesn't change. From the red/green wire to the black green it reads 4.97 volts. I know its supposed to be 5v and when trying to adjust it the voltage never changes. I can push the TPS from one side to the other but it will not change at all. Sign of a bad TPS? I also checked from the white/green to the red/green and got a steady 1v. Which I know its supposed to be from. 48 to. 52 but that will not change either. Anyone have any idea?

Anyone?

sounds like a bad TPS. good luck

Red lead reads the middle wire while the black is connected to the end wire. With key ON, black lead is on wire one while the red lead is getting voltage from the middle wire.

The way we describe the wire colors are main color/stripe color.
The Green/Black goes to TPS pin 4 and is Ground.
The Green/Red goes to TPS pin 1 and is the +5v sensor power from the ECU (4.97v is close enough)
The Green/White goes to TPS pin 2 and is the TPS output voltage. On the car it should vary from ~0.5v to ~5.0v as the throttle is turned when measuring between it and ground (between the G/W and G/B wires)

Try measuring again using the correct wires.
