The manifold absolute pressure sensor (MAPS) detects the pressure of air drawn into the engine cylinder. DENSO’s MAPS accurately detects the pressure, even if the surface of the sensor is dirty.

DENSO provides various pressure sensors including an atmospheric pressure sensor, brake booster sensor, MAPS, exhaust gas pressure sensor, refrigerant pressure sensor, and common rail pressure sensor.

DENSO Technologies – Leading the World

• In 2003, DENSO introduced the world’s smallest MAPS that has a sensor and a processing circuit directly mounted to a case. The sensor chip is covered with a newly developed gel to accurately detect pressure even when the sensor surface is dirty.

Benefits and Features

• Small size and high reliability
  • The MAPS has a sensor and a processing circuit directly mounted to the case, resulting in small size.
  • The processing circuit is integrated with a noise filter for static electricity and electromagnetic waves, minimizing the number of connections.
• High detection accuracy
  • The sensor chip, covered by a newly developed gel, accurately detects pressure even when its surface is dirty.
  • The output has a ratio property relative to the power source voltage.
• Easy installation
  • The MAPS can be directly installed in the intake manifold.
