Okay, so value right now .10v with no TPS sensor connected. Greattttt wiring issue. I have already checked ground as suggested in other threads.
With the ign on I measured the following:
Green/Yellow = 4.78 volts
Brown/Red = -.08 volts (that's right,negative)
Yellow/Red = 4.32 volts
Were you measuring relative to chassis ground or the black wire (ECU sensor Ground)?
G/Y is ECU sensor +5v. Seems a little low but it's all about where your measuring between since the measurement is the relative potential difference between two points.
BR/R is TPS output voltage.
Y/R is IPS. This signal has a pull-up to +5v inside the ECU and the TPS grounds it when the IPS closes.
The ECU measuring 0.1v when the TPS isn't connected isn't what I'd like to see but it's less that the 26% you were getting before.
With the TPS still off the TB but connected to the ECU what does DSMLink read?
