Mixture Ratio Feedback System: Description
The Electronic Concentrated Engine Control System (ECCS) is a computerized emission, ignition and fuel control system. A single control unit monitors a variety of sensors, including the following:
- Crankshaft Angle Sensor
- Throttle Valve Switch
- Air Flow Meter
- Air Temperature Sensor
- Cylinder Head Temperature Sensor
- Barometric Pressure Sensor
- Oxygen Sensor
- Detonation Sensor
- Vehicle Speed Sensor
- Park/Neutral Switch
- Air Conditioning Switch
The computer processes information from these sensors and controls these engine functions:
- Ignition Timing and Dwell
- Fuel Injectors
- Fuel Pump Operation
- Engine Idle Speed
- EGR Operation
