The manifold pressure sensor, commonly referred to as the MAP sensor, is a critical component in modern internal combustion engines. It plays an essential role in ensuring optimal engine performance by measuring the pressure inside the intake manifold and relaying this information to the Engine Control Module (ECM). This data helps the ECM determine the correct air-fuel mixture, ignition timing, and other parameters necessary for efficient engine operation. In this article, we will explore how a manifold pressure sensor works, why it is important, its types, common issues, and troubleshooting methods.
