More TPS basics:
The slots for the two mounting fasteners allow initial calibration when replacing a TPS.
With ignition on, stop/run on, the center position pin (black/red wire) probed with voltmeter + lead, with - lead connected to ground, voltage at closed throttle should be 0.5 vdc. If not, rotate unit to read 0.5 vdc. The reading then should be 4.5 vdc at WOT (wide open throttle).
Opening throttle slowly should result in a smooth voltage increase from closed to WOT.
