On a Citroën Picasso Xsara, the map sensor (Manifold Absolute Pressure sensor) is typically located on or near the intake manifold. It is often mounted on the throttle body or the intake duct, depending on the engine configuration. To locate it, look for a small sensor with an electrical connector, usually near the air intake system. Always consult the vehicle’s service manual for precise location details specific to your model and engine type.
