Fault Detection/Management

WARNING: This page does not describe the selected car, but rather 8 other vehicles, including the 2005 Ford RV Cutaway, 2005 Ford Pickup, 2005 Ford F550 Super Duty, 2005 Ford F450 Super Duty, and 2005 Ford Excursion. However, it is still accessible from the selected car via links, so may be relevant.

A MAP signal that is detected by the PCM to be out of range or at an incorrect value for specific conditions causes the PCM to ignore the MAP signal and operate the engine from an inferred boost pressure signal.

CAUTION: The PCM harness connectors must be properly seated and the connector latch properly attached to eliminate possible driveability concerns or a no start condition. Installing the PCM connectors on an angle may cause an improper connection, misdiagnosis, and damaged components. Install the connector until the lever pivots and seats itself. Apply light pressure to get the connector into position on the PCM and then fully seat the connector.
NOTE: Visually inspect the harness connectors for corrosion, damage, proper mating, and correct pin tension.
