– what is MAP sensor and how work in suzuki mehran

1- What is map sensor can see in pic

The MAP sensor detects the intake manifold pressure from the throttle valve to indirectly calculate the volume of intake air based on the relationship between pressure and engine rotation speed.

2-The MAP sensor is a compact semiconductor vacuum sensor that uses properties   that change the electrical resistance when pressure is applied to silicon (single crystal). Thus, the MAP sensor puts multiple pressures on the engine ECU in the form of an electrical signal. Intake air volume is calculated from these electrical signals to control the correct fuel ratio.
