Air-Fuel Ratio Sensor: Precise Engine Performance

The air-fuel ratio sensor is essential for modern engine management. It constantly measures the amount of oxygen in your exhaust and helps the vehicle’s computer (ECU) to keep the fuel mixture at its ideal level. This balance gives you the best mix of fuel efficiency and low emissions 🌱.

How This Sensor Works

The sensor sits in your exhaust pipe and sends real-time voltage signals to the ECU. These signals tell the computer if the engine is running rich (too much fuel) or lean (too much air). The ECU then adjusts the fuel injection timing and amount for smooth running and proper combustion.

What Happens If This Part Fails?

• Check Engine Light comes on ⚠️
• Poor fuel economy
• Rough idling or engine hesitation
• Failed emission test

Replace this sensor promptly to protect your engine and save on fuel costs.
