Air-Fuel Ratio Sensor: Essential for Engine Efficiency ⚙️

Why Is This Sensor Needed?

The air-fuel ratio sensor is a vital component for your vehicle’s engine management system. It measures the exact mix of oxygen and fuel in the exhaust gases, helping your car’s computer (ECU) adjust the fuel injection for optimal performance, efficiency, and emission control. Accurate readings ensure better fuel economy and lower harmful emissions.

How Does the Sensor Work?

This sensor uses advanced zirconia or similar technology to instantly detect the air-fuel mix leaving the engine. It sends real-time electrical signals to the ECU, which then tweaks the fuel delivery. This constant feedback loop keeps your engine running smoothly and within environmental standards.

What Happens If the Sensor Fails?

• Increased fuel consumption
• Poor engine performance
• Check engine light on
• Failed emission tests
• Rough idling or stalling
