The Turbocharger/Supercharger Boost Sensor A Circuit sensor is the MAP - Manifold Air Pressure sensor.

You can find the MAP on the large intake pipe after the turbo.


This is the MAP sensor on a C3 diesel, the picasso will be similar. Look for the sensor on the intake, that comes after the turbo.
