Feedback Carburetor Electronic Engine Control System: Description: Notes

Ford 2.3 Liter engine equipped vehicles sold in California (both Turbo and non-Turbo engines) use a Feedback Carburetor Electronic Engine Control System. The main components of this system are a dual catalytic converter, a Thermactor air control system, and an electronic feedback controlled carburetor.

In operation, an electronic Microprocessor Control Unit (MCU) monitors exhaust gas composition with the Exhaust Gas Oxygen (EGO) sensor and commands carburetor main metering mixture for best exhaust gas emission control.
