A Manifold Absolute Pressure (MAP) sensor is a crucial component in a vehicle's engine management system, responsible for measuring the pressure within the intake manifold. This data is transmitted to the engine control unit (ECU), which uses it to calculate the air density and determine the optimal air-fuel mixture for combustion. By accurately monitoring the intake manifold pressure, the MAP sensor helps ensure efficient engine performance, improved fuel economy, and reduced emissions. Proper functioning of the MAP sensor is essential for maintaining engine power and responsiveness, as well as preventing issues such as poor acceleration and engine knocking.
