White? There is no white wire. There is a gray wire and that is the wrong one. You should have the black lead on the black wire and the red lead on the blue wire.

Perform the same test on the same wires at the pcm and see if you get the same results.

If you're absolutely sure that that code is resetting immediately, then you have a bad PCM. It would be better if you had a scanner to look at the TPS numbers that the PCM is seeing.

There's such thing as manufacturers defects who knows or you did something wrong that caused it to malfunction-have the computer further checked and tested-
