Intake Manifold Pressure (Map) Sensor
The Manifold Absolute Pressure (MAP) sensor is used for the Speed Density air charge calculation.
The MAP sensor is physically integrated with the Intake Air Temperature 2 sensor. The MAP sensor has a specified range of 10 to 200 kPa. The voltage is electrically clipped between 0.3 to 4.8 volts,
