ECC CEC System: Description

The Electronic Concentrated Engine Control System (ECCS) is a computerized emission, ignition, and fuel control system. A single electronic control unit (ECU) monitors a variety of sensors, including the following:

• Mass Airflow Meter
• Crankshaft Angle Sensor
• Temperature Sensor
• Detonation Sensor (Turbo Models)
• Exhaust Gas Oxygen Sensor
• Park/Neutral Switch
• Throttle Valve Switch
• Vehicle Speed Sensor
• Air Temperature Sensor
• Fuel Temperature Sensor
• Vacuum Control Sensor
• Power Steering Oil Pressure Switch

The computer processes information from these sensors and controls the following engine functions:

• Air Injection
• Air Regulator Control
• EGR Operation
• Engine Idle Speed
• Fuel Injectors
• Fuel Pump Operation
• Ignition Timing
• Mixture Ratio
• Denotation
• Fuel Pressure
• Auxiliary Air Control
• Airflow Meter Self-Cleaning
• Spark Plug Switching
• Mixture Heating
• Canister Purge
• Self-Diagnosis (Fail-Safe Operation)
