If you're looking for a flat spot in the TPS, you're not going to read voltages. That's a secondary measurement usually used to check adjustment of the thing.
You want to grab an analogue ohmmeter (one with a sweep needle,) and check for actual changes in the resistance of the thing while you're moving the sensor's lever. The reason for using an analogue meter is simple - digital meters have buffer circuits built into them that delay readings, and you'll get a 'false fail' from using a digital.
When checking for a flat spot, absolute readings are not important. What you're looking for is a smooth change in resistance that paces along with the motion of the sensor's lever - if it hitches, skips, or sticks; you're looking for a replacement sensor.
