Signal Functions

WARNING: This page does not describe the selected car, but rather 10 other vehicles, including the 2002 Ford RV Cutaway, 2002 Ford Pickup, 2002 Ford F550 Super Duty, 2002 Ford F450 Super Duty, and 2002 Ford Excursion. However, it is still accessible from the selected car via links, so may be relevant.
NOTE: ECT sensor is used only on manual transmission equipped vehicles.

Engine Coolant Temperature (ECT) sensor is used as primary input to Electronic Control system to enable adaptive cooling. This provides a means of providing adequate cooling in severe engine temperature conditions. When ECT is more than 225°F (107°C), fueling rate of engine is modified to provide cooling protection and prevent engine damage due to overheating.
