Delphi Manifold Absolute Pressure/Manifold Air Temperature (MAP/MAT) Sensors
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:
- 15 kPa to 102 kPa
- 12.5 kPa to 115 kPa
- 20 kPa to 250 kPa
- 10 kPa to 350 kPa
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:
- One voltage output proportional to engine intake manifold pressure
- Thermistor output proportional to manifold air temperature
