OBD vs Fuel Sensors

How They Work and Why Fleets Need Both

What is OBD?

OBD (On-Board Diagnostics) connects to the engine ECU – Tracks engine performance – Estimates fuel usage – Monitors driver behavior

What is a Fuel Sensor?

Fuel sensors measure fuel inside the tank – Tracks exact fuel levels – Detects refueling events – Identifies fuel theft or leaks

Key Difference

– OBD = Estimated fuel data (85–90%) – Fuel Sensor = Actual fuel data (up to 99%)

Why Fleets Need Both

Using both systems together with Taabi: – Detect fuel theft instantly – Improve fuel efficiency (10–15%) – Reduce costs & downtime
