The Delphi Manifold Absolute Pressure/Manifold Air Temperature (MAP/MAT) Sensors provide precise measurements of manifold absolute pressure, manifold air temperature, and other high output gasoline and diesel engine performance characteristics, in the following operating pressure ranges:
Delphi Manifold Absolute Pressure/Manifold Air Temperature Sensors are designed to perform in harsh environments such as extreme temperatures and vibration, thermal and mechanical shock, and chemical contamination. They provide two separate outputs critical to air/fuel ratio optimization:
Delphi Manifold Absolute Pressure/Manifold Air Temperature Sensors can be used for manifold absolute pressure, barometric pressure, and exhaust gas recirculation (EGR) pressure applications in gasoline and diesel engine programs.
Delphi MAP/MAT Sensors can be used in other non-automotive gaseous pressure applications within appropriate ranges.
