    what is the function of a map sensor in 2001 town and country

      MAP sensors measure barometric absolute pressure in the intake manifold. By calculating the mass of the air going into the engine, air temperature, and the rotations per minute of the engine, the engine’s ECU can determine the density of the air flowing into the fuel mixture. The ECU can then adjust air flow or fuel flow.
