6.4L Power Stroke Electrical – MAP (Manifold Absolute Pressure)

• The MAP sensor is a three (3) wire variable capacitance sensor.
• The ECM uses the MAP sensor signal to assist in the calculation of EGR duty cycle, Fuel Delivery, and Throttle             Body Position.
• The ECM measures the MAP signal to determine intake manifold (boost) pressure.

NOTE: Washing a hot engine can have negative effects on this sensor!
NOTE: The 6.0L engine used a remote mounted MAP sensor.
NOTE: Pay special attention to differentiating between the MAP sensor and the EP sensor, do not interchange them!
