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?

Figured it out.

that's what I get for assuming the harness was made properly lol.

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.
