What’s the Difference Between an O2 Sensor and a MAF Sensor?

The O2 sensor is used to measure the oxygen content of a vehicle’s exhaust, while the MAF sensor measures the mass airflow flowing into a vehicle’s engine.

O2 Sensor Vs Maf Sensor

An O2 sensor and an MAF sensor are both parts of a vehicles emission control system. Together, these sensors work to monitor and regulate the air/fuel mixtures in the engine, helping to make sure that the engine does not generate too much poisonous emissions or produce poor performance. However, despite their similar purpose, the two sensors have different methods of operation and monitoring.

The O2 (or oxygen) sensor uses an electrochemical reaction to measure the amount of oxygen present in exhaust gases that flow through it. After measuring the oxygen levels, it will then send signals to the electronic control unit (ECU) telling it how to adjust air-fuel ratio accordingly.

On the other hand, a mass airflow (MAF) sensor works by using heated probes to measure air flow coming into the engine. The signal is then sent to the ECU — this data is used to update how much fuel is added into each cylinder as it fires up. This allows for more precise fuel management and less emissions due to a more consistent air-fuel mixtures throughout combustion.

Overall, both sensors serve a similar purpose – though in different ways. By having both systems at work together, auto makers are able to ensure clean emissions and optimal performance for their vehicles.
