Ford TP (Throttle Position) Sensor Voltage vs. Angle Graph – 1992 Bronco

This document is a Throttle Position (TP) sensor reference graph, likely a page from a Ford service manual (figure reference TB-4028-A). It plots TP sensor signal voltage against throttle shaft rotation in degrees (TP rotational angle). A note states that the normal range of throttle angle measurement for the TP sensor is 0 to 85 degrees. The graph shows a linear relationship between throttle rotation and output voltage, with plotted data points at approximately 13, 26, 39, 52, 65, 78, and 81 degrees, corresponding to voltages ranging from roughly 0.601 V near closed throttle up to about 4.538 V near 84 degrees of rotation. A ±3% tolerance band is drawn as dashed lines on either side of the nominal line, indicating acceptable sensor variation. Beyond about 84 degrees / 4.538 volts, the graph marks a region labeled "OVER-TRAVEL PERMISSIBLE," indicating the sensor may travel past the normal measurement range without fault. A technician can use this chart to verify that measured TP sensor voltage at a given throttle angle falls within the specified ±3% tolerance, helping diagnose a faulty or misadjusted TP sensor.
