Map sensor wiring voltage?

[dj-rix]

Some idiot fitted an FCD right next to the Ecu and removed it leaving the wires in a mess, blobs of solder and electrical tape. Any way to test that the wires are ok and not giving a dodgy signal/ voltage to the map sensor?

I'm guessing it's the green wire mate? Well is on my GT, I have got it sorted as took my fcd off idiot before done a crap job too

There's three wires to a map sensor - stable 5v feed (VCC), signal ground (E2 or E21 pin usually depending on which series ecu) and the map signal back to the ecu (PIM).
