MAP Sensor Wiring HELP!

[BamaS6]

Does anyone know which wires are for power, signal, and ground on a '13 A5?

I have the following colors: Yellow, Gray/Yellow, and Brown/Green.

Thank you!

EA888 Gen2 2.0T (CAE, CPM) doesn't use a MAP, it uses a MAF. And the MAF doesn't use that connector.

That looks a lot more white/green than brown/green. But I don't find any white/green on a 4-pin, except for the V8 cyl 1 ignition coil. Maybe something got messed up in the image processing.

Best guess is you mean the G31 charge air pressure sensor. Should be on the intake hard pipe down below the ABS unit. While that is an absolute pressure sensor of an air stream, it's not after the throttle valve, so it's not a G71 intake manifold pressure sensor (MAP).

ECM supplied 0V on 1 (brown/green)
ECM supplied 5V on 3 (gray/yellow)
output signal to ECM on 4 (yellow)
