Ford EEC-IV TPS Pinpoint Test DH Schematic - TP Sensor Connector Pinout

This page (17-77) is from a Ford EEC-IV Pinpoint Test Procedures manual, covering Pinpoint Test DH for the Throttle Position (TP) Sensor. It presents the "Pinpoint Test Schematic" showing how the TP sensor circuit connects to breakout box test pins: Test Pin 46 for SIG RTN (signal return), Test Pin 47 for TP (throttle position signal), and Test Pin 26 for VREF (reference voltage). A branch from the TP signal wire is noted as going "to 4EAT module for 1.9L MA A/T and 3.0L Probe A/T" applications. The diagram illustrates both the standard TP sensor vehicle harness connector and TP sensor connector (oval 3-pin style), as well as an alternate TP sensor vehicle harness connector and alternate TP sensor connector (round style) with the same three circuits: SIG RTN, VREF, and TP. Footnotes state that the asterisked test pins are located on the breakout box and that all harness connectors are viewed into the mating surface. The figure reference number is A13541-A. Faint mirrored bleed-through from the reverse page shows an application/wire-color table listing engines such as the 4.9L, 5.0L, 5.8L, and 7.5L F-Series/Bronco.
