Electronic Engine Control III: Description
NOTE:
Electronic Engine Control III (EEC III) is used in 1982 on Ford Motor Co. passenger cars with 5.0L Electronic Fuel Injection (EFI) engines, as well as on some light trucks with feedback carburetors. For passenger car application, disregard information in this article on feedback carburetors.
The EEC system consists of an Electronic Control Assembly (ECA), several sensors located on the engine or in the various engine systems, special actuators governed by the ECA, and various connecting electrical and vacuum lines. This system adjusts the engine to the best settings for various conditions of load, speed, temperature and altitude by controlling the following functions:
- Ignition Timing
- Carburetor Air/Fuel Ratio
- Engine Speed At Idle
- Exhaust Gas Recirculation (EGR) Flow Rate
- Secondary (Thermactor) Air Flow Rate
- Fuel Evaporation Canister Purging
