Your Ford Fiesta's Manifold Absolute Pressure (MAP) sensor is positioned on the left side of the engine bay, attached to the intake manifold. This sensor plays a critical role in regulating the air intake to ensure optimal engine timing. If the sensor malfunctions, you may experience sluggish engine performance or reduced acceleration, which can eventually lead to engine damage and potential failure. A replacement sensor typically costs around $200. It is recommended to replace it promptly to avoid more costly engine repairs. While installing the sensor yourself is manageable, you also have the option to have it professionally installed for an additional $100.
In the 2011 Ford Fiesta, you can find the map sensor positioned within the intake manifold.
