How OBD2 Helps Detect Engine Air-Fuel Ratio Instability
The air-fuel ratio is critical for efficient combustion. Even small imbalances can reduce engine performance and increase emissions. OBD2 air-fuel ratio diagnostics help detect instability in this balance. Importance of Proper Air-Fuel Ratio Maintaining the correct ratio ensures: Efficient combustion Better fuel economy Reduced emissions How OBD2 Detects Ratio Issues OBD2 systems monitor oxygen sensor data and fuel trim values. Irregular fluctuations may indicate instability.
