Which PCM pin does the Throttle Position Sensor (TPS) signal go to on the 5.0L?

The TPS signal is circuit 355 (GY/W wire), running through connector C1024 and C101 to PCM pin 47.

What wire color is the shared sensor reference voltage on the 5.0L engine controls diagram?

Circuit 359, a GY/R (gray/red) wire, feeds the ECT, IAT, TPS and EVP sensors via splice S161, with variants noted for with/without E4OD or 4R70W transmissions.

What circuit and PCM pin does the knock sensor use?

The knock sensor (KS) uses circuit 310, Y/R wire, through connectors C1009 and C101 to PCM pin 23.

What does the EGR Valve Position (EVP) sensor do according to this diagram?

It indicates EGR valve position to the PCM by providing a voltage signal proportional to EGR position, depending on engine operating condition. Its wiring is 351 BR/W and signal return 352 BR/LG to PCM pin 27.

Where do the bottom PCM circuits 382, 259, 929 and 395 lead?

PCM pins 4 (382 Y/BK), 16 (259 O/R), 30 (929 PK) and 56 (395 GY/O) lead to the Ignition System, referenced on Page 21-1.

This document is page 24-5 of a Ford wiring diagram set, titled "Engine Controls, 5.0L." It shows the sensor input wiring to the Powertrain Control Module (PCM, connector C185) for a 5.0L engine. Sensors covered include the Knock Sensor (KS, C1009), Engine Coolant Temperature (ECT) Sensor (C183), Intake Air Temperature (IAT) Sensor (C164), Throttle Position Sensor (TPS, C1024), and EGR Valve Position (EVP) Sensor (C182). A shared reference voltage circuit 359 (GY/R wire) feeds the ECT, IAT, TPS, and EVP sensors through splice S161, with alternate routing noted for vehicles with or without E4OD or 4R70W transmissions. Signal circuits shown are 310 Y/R (knock, PCM pin 23), 354 LG/R (ECT, pin 7), 743 GY (IAT, pin 25), 355 GY/W (TPS, pin 47), 351 BR/W and 352 BR/LG (EVP, pin 27), plus an unused 330 Y/LG circuit at pin 24. Bottom PCM pins 4, 16, 30, and 56 carry circuits 382 Y/BK, 259 O/R, 929 PK, and 395 GY/O to the Ignition System (Page 21-1). Explanatory callouts describe how each sensor works and how the PCM uses its signal.
