Ford Speed Sensor AC Voltage Test Diagram – Meter Hookup (GH1953-B)

This document is a purely graphical service-procedure illustration identified by the figure number GH1953-B. It contains almost no text; the only legible labels are 'AC' and the polarity markings '(+)' and '(−)' on two meter faces. The upper illustration shows a close-up of a two-pin electrical connector (a round sensor connector with two terminals) with test leads from an AC voltmeter/multimeter probing its two pins. The lower illustration shows the same AC meter connected to a small two-terminal sensor mounted on top of what appears to be a transmission/transfer case or axle housing, indicating where the component is located on the vehicle and how to back-probe or connect the meter at the sensor. A reader can learn the correct hookup for testing a two-wire sensor (such as a speed sensor) by measuring its AC voltage output: connect the meter's positive and negative leads across the sensor's two pins, either at the disconnected connector or at the sensor on the housing. No fuse data, wire colors, torque values, part numbers (other than the figure code), specifications, or vehicle year/model applicability statements appear anywhere in the image.
