1️⃣ What is EFI (Electronic Fuel Injection)?
EFI is a system that electronically controls fuel delivery to the engine using sensors and a computer called the ECU (Engine Control Unit).
Instead of a traditional carburetor, the ECU calculates the exact amount of fuel needed for efficient combustion.
Benefits of EFI:
- Better fuel efficiency ⛽
- Improved engine performance 🚗
- Lower pollution/emissions 🌱
- Easier engine diagnostics

An EFI technician works with many vehicle electronic components:
Sensors
Sensors send information to the ECU:
- MAF Sensor – Mass Air Flow
- MAP Sensor – Manifold Absolute Pressure
- TPS – Throttle Position Sensor
- Oxygen Sensor (O2)
- Engine Temperature Sensor
Actuators
These parts act based on ECU commands:
- Fuel injectors
- Idle air control valve
- Ignition coils
Other Systems
- Engine Control Unit (ECU)
- OBD-II diagnostic system
- Car wiring harness
