Delphi EFI System: Troubleshooting and Maintenance
Electronic fuel injection has seven basic advantages.
1. Improved Fuel Mileage of 10% to 15%
2. Improved starting and cold engine performance without engine warm-up
3. Improved acceleration and smoother throttle performance
4. ECU protects engine components while operating at high engine temperatures and rpms
5. Improved engine performance with varying temperatures and elevations
6. ECU provides diagnostic trouble codes to facilitate troubleshooting of engine problems
7. Cleaner engine emissions
Delphi EFI System Design
Delphi EFI employs 5 sensors to monitor engine performance.
1. Crankshaft Position Sensor
2. Coolant Temperature Sensor
3. Oxygen Sensor
4. Throttle Position Sensor
5. Manifold Air Pressure/Manifold Air Temperature (MAP/MAT) Sensor
Delphi EFI employs the following system components.
1. MT05 Engine Control Unit (ECU)
2. Fuel Pump
3. Multec 3.5 Fuel Injector
4. Idle Speed Control Valve (Idle Stepper Motor)
5. Multec Ignition Coil
