Powertrain Management: Description and Operation

Circuit Description
The Multiport Fuel Injection (MFI) control system is an electronic fuel metering system with fuel injectors near the inlet ports of each cylinder. The amount of fuel injection is determined by the ECM. The emission control system includes oxygen sensors and catalytic converters (unleaded fuel only).

The MFI's three major functions are air-fuel mixture, idle speed control and ignition timing control. See the work shop manual engine control section for troubleshooting procedures.
