The TPS is tested by using resistance values, but is adjusted by reading the output voltage at idle. See page 6-10 of your manual. The engine is run at 2000 rpm, and DCV is measured between the yellow (+) and black leads by back probing them while they are connected. The values should be 0.58-0.78 DCV.
