Air-Fuel Ratio Measurement Sensor

Why Is This Sensor Needed

Modern engines rely on precise air and fuel mixture for performance and emission control. This sensor monitors the ratio, sending real-time data to your car’s computer. Correct information is vital for efficient combustion, optimal power, and low fuel consumption.

How Does It Work

Positioned in the exhaust stream, this sensor constantly checks oxygen levels in outgoing gases. It responds quickly to changes, allowing the ECU to adjust fuel injection and maintain the perfect air-fuel mix, no matter driving conditions.

What If This Sensor Breaks

A faulty air-fuel sensor can cause poor fuel efficiency, unstable idling, engine hesitation, and increased emissions. Prolonged defects may damage the catalytic converter or trigger the engine warning light.
