The Manifold Absolute Pressure(MAP) sensor measures the change of pressure in the intake manifold. The pressure of intake manifold is changed as variable engine running condition and converted into voltage and then it is monitored by the ECM.
ECM sets DTC P0107 if the ECM detects signal voltage lower than threshold of the possible range of a properly operating MAP sensor.
