NOTE: The descriptions and specifications contained here were in effect at the time it was approved for printing. Ford Motor Company reserves the right to discontinue models at any time, or change specifications or design without notice and without incurring obligation.

The Manifold Absolute Pressure (MAP) sensor is integral to the Compuvalve. It is a pressure transducer that converts pressure to voltage through a piezo-resistive element. It is attached to the intake manifold via a vacuum line with a damper tube that is routed to an external hose barb on the Compuvalve. MAP is used to monitor engine operating state.
