That is not a map sensor it's an atmosphere pressure sensor. That sensor is located inside the ECU, you will probably be better off replacing the ECU over the sensor.
Ominous is right.
Also, people have been giving you hints to do research for yourself. If you had looked on Honda Tech like you were suggested to do, you would have found out in 5 minutes.
