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!
