Ford MAP Sensor Connector Pinout Diagram - VOLT REF, MAP, SIG RTN

This document is a simple line-art diagram of a Ford Manifold Absolute Pressure (MAP) sensor, shown from the connector face. The sensor body is drawn with its two mounting ears/brackets and a keyed three-pin electrical connector. Callout lines identify each of the three connector terminals: the left pin is labeled VOLT REF (voltage reference), the center pin is labeled MAP (the sensor's signal output), and the right pin is labeled SIG RTN (signal return/ground). The caption at the bottom reads "MANIFOLD ABSOLUTE PRESSURE SENSOR." A reader can use this diagram to identify the pinout of the three-wire MAP sensor connector when testing or diagnosing the sensor circuit — for example, determining which terminal should carry the reference voltage, which carries the sensor output signal, and which is the return ground. The document contains no part numbers, wire colors, voltage specifications, torque values, or year/model applicability information; it is purely a connector terminal identification diagram. It was uploaded to a 1990 Ford Bronco gallery as part of a larger set of EFI and wiring reference scans, consistent with speed-density Ford EFI diagnostics.
