TPS Adjustment from 50Trippin

[Sidewayz6.0]

Throttle Position Sensor "The throttle position sensor is housed on top of the throttle body. This rotary-potentiometer-based device sends a voltage signal to EEC to indicate the position (and rate of change of position) of the throttle shaft. Ford service literature shows that a five-oh's throttle position sensor's signals range between .6 and 4.585 volts, the lower number indicates that the throttle is closed and the higher signaling wide-open throttle. With the engine off and the ignition key switched on, a digital voltmeter connected across the sensor's wires should read .85-1 volt. At idle, a reading of .98-1 volt is considered desirable for performance service. A TPS setting of 1 volt at idle produces 4.6-4.8 volts at wide-open throttle. Adjustment involves loosening the pair of screws that attach the sensor to the throttle housing and rotating the sensor until the meter reading is corrected. The meter's positive lead connects to the sensor's green wire and the negative lead goes to the black wire. Due to variations in production equipment, the holes in the sensor housing may require elongation before it becomes possible to obtain the desired reading. For reference, the 1994-1995 TPS uses different-colored wires, and the hold-down holes in the sensor housing are not accessible as on previous models. In July 1989, Ford issued a Technical Service Bulletin covering hard-to-remove throttle position sensor mounting screws."
