Default TPS Results

I put a new fuse in my DMM and it works so I did a Throttle Position Sensor tests. I did all these tests while KOER.

I first was able to back probe into the wiring harness connector that is closes to the sensor. But I was only able to get a connection with the green wire, which is the name of TP SIG. I tested it from idle to WOT. It looks like 0-5 volts smoothly.

I then wasn't able to back probe the orange wire, which is the Voltage Reference wire. So I jumped the orange wires and also jumped the green wires. The orange wire is consistant 5 volts through out idle and WOT.

Finally I did the black wire, which is the Signal Return wire I measured the return from the sensor and received a constant 4 1/2 Volts through out idle to WOT. There was one time I received 4 1/2 to 5 1/2 Volts from idle to WOT.

What do you think PKRWUD? Is the TPS toast.
