Default Inverted vTPS value

I know this subject is beaten to death from what I gathered from the search results. The common mistake is mixing the vRef and ground wires.

I followed Joe's thread in creating the harness, and diyauto's manual to mod the mspnp. I have confirmed that wiring and modifications are correct.

Could a bad sensor possible give off inverted values? Closed position was around 240, and WOT was around 40. I need to find my multimeter to confirm if the sensor is bad. What are the ohms range for the Bosch 0280120406 vtps?

there is no harness in the MSPNP.

so if you really had a MSPNP, and had this issue, the issue was in the wiring.

Sorry, I meant the vtps connecter since it connected to the oem harness. The previous owner switched ground and power around, and I (retarded me) did not double check.

Had pin 1 and pin 2 mixed up.
