6.7L Power Stroke – Manifold Absolute Pressure (MAP)

The MAP sensor is a 3-wire variable capacitance sensor. The PCM supplies a 5 volt reference (VREF) signal which the MAP uses to produce a linear analog voltage that indicates pressure.
The MAP sensor is used for turbocharger, EGR, and regeneration control.
IDS: MAP (volts) and MAP_A (pressure)
