Ford Transmission Range Sensor Wiring Diagram - 60-Pin PCM Pins 30 & 46

This document is a wiring schematic (labeled "Figure 1") showing a transmission range sensor circuit connected to a vehicle controller. On the left is a drawing of a 60-pin controller connector viewed from the pin side of the chassis harness, with corner pins labeled 20, 40, 60 across the top and 1, 21, 41 across the bottom to establish pin numbering orientation. Two wires run from the connector to the sensor: a Power lead identified as Pin 30 and a Ground lead identified as Pin 46. On the right is the internal schematic of a rotary switch/resistive sensor with a wiper contact that moves across positions labeled P, R, N, D, 2, and 1, corresponding to gear-selector positions Park, Reverse, Neutral, Drive, 2, and 1. Each position taps into a chain of series resistors, so the voltage seen at the controller varies depending on the selected gear position. A reader can learn which controller pins carry power and ground for this sensor (Pins 30 and 46 of the 60-pin connector), how the 60-pin connector is numbered when viewed from the pin side, and how the sensor internally uses a resistor ladder to signal gear position. The document contains no wire colors, part numbers, or stated vehicle applicability.
