A well functioning MAP sensor ensures that your vehicle runs efficiently maintaining performance and reducing emissions Understanding the wiring diagram of a 3 wire MAP sensor can be incredibly beneficial whether you re troubleshooting an issue or simply want to understand your vehicle better The Basics of a 3 Wire MAP Sensor Wiring diagram for a GM 3 bar map sensor A GM 3 bar map sensor is a vital component in a vehicle s electronic engine management system It measures the intake manifold pressure which helps the engine control unit ECU optimize fuel injection and ignition timing Wiring the sensor correctly is crucial for proper functionality and accurate
Pin 1 seems to be ground as the diagram says so I ve measured with respect to that Pin 2 measures a steady 2 25v and Pin 4 a steady 1 83v both with the engine idling and off Pin 3 was varying quite a bit between 1v and 4 5v if i recall Wiring Diagram Info Request Map Sensor 3rd and 4th gen I have a 3rd gen engine wiring wit a cut map sensor I bought a 4th gen map sensor with pig tail On the gen4 the brown wire goes to ground pin 1 the gray wire is the 5V from the ECU pin 3 and the green black is the signal wire pin 2 Hope to help Sam Save Share
