Fault Detection/Management

WARNING: This page does not describe the selected car, but rather 8 other vehicles, including the 2006 Ford RV Cutaway, 2006 Ford Pickup, 2006 Ford F550 Super Duty, 2006 Ford F450 Super Duty, and 2006 Ford Econoline. However, it is still accessible from the selected car via links, so may be relevant.

An IAT signal that is detected out of range high or low by the PCM causes the engine to ignore the IAT signal and assume an ambient temperature of 25°C (77°F).
