Understanding Air Fuel Ratio Sensors ?️

The Air Fuel Ratio Sensor is a crucial component for maintaining optimal engine performance in modern vehicles. This sensor precisely measures the air-to-fuel ratio present in the exhaust gases, ensuring the engine combusts fuel efficiently. A perfectly balanced air-fuel mixture is key to maximizing power output, reducing emissions, and achieving better fuel economy.

Functionality of the Sensor

The sensor operates by sending voltage signals to the Engine Control Unit (ECU). These signals help the ECU adjust the fuel injection levels and maintain an ideal combustion process. By accurately monitoring the air and fuel mixture, it ensures the engine operates within optimal parameters, promoting longevity and performance.

Consequences of a Malfunctioning Sensor

If the air fuel ratio sensor fails, several issues arise. The vehicle may experience poor fuel economy, increased emissions, and a noticeable decrease in engine performance. In severe cases, a faulty sensor can even lead to engine stalling or failure to start, as the engine will run too rich or too lean, harming internal components over time.
