Manifold Absolute Pressure Sensor (MAP)
A sensor that measures intake manifold pressure to determine engine load.
The MAP sensor provides data on manifold pressure, allowing the ECU to adjust fuel delivery and ignition timing. Vacuum leaks or sensor faults cause poor acceleration or rough idling. Replacing a damaged sensor restores performance. MAP and MAF sensors work together for precise engine management. Keeping the intake clean ensures accurate readings.
