Manifold Absolute Pressure Sensor for Vehicle

摘要

The present invention relates to a map sensor for a vehicle for measuring an amount of intake air for determining a fuel injection amount of the vehicle. More specifically, a sensor chip adheres to a recessed part of a front surface of a sensor body formed of a synthetic resin material with adhesive and covered with a silicone protection part after the sensor chip and a lead frame are connected with an aluminum wire, and an air hole measuring the amount of intake air is formed while the intake air is introduced to the rear surface of the sensor main body so as to be installed at a position opposite to a conventional art such that a carbon component flows into a front surface of a conventional sensor body together with the intake air and is deposited on a silicone gel and the sensor chip, and also a problem of corroding the aluminum wire and the lead frame metal can be simply solved, thereby capable of improving greatly a reliability of the sensor.
