A-Premium Engine Manifold Absolute Pressure (MAP) Sensor — Direct-Fit OE Replacement for GM Vehicles

The A-Premium Engine Manifold Absolute Pressure (MAP) Sensor is a direct-fit replacement sensor engineered to restore accurate intake pressure readings for compatible GM, Buick, Cadillac, Chevrolet, Hummer, Saab and Isuzu models.

When the intake manifold pressure sensor fails or drifts, engine performance and fuel trim can become inconsistent. This A-Premium MAP sensor is manufactured as a plug-and-play component designed to match OE electrical and mounting points so installation is straightforward and requires no special calibration on most vehicles. It targets mid-2000s through early-2020s GM-family vehicles that originally used the referenced OEM part numbers.
