Air Fuel Ratio Sensor Guide 🚗

Why This Sensor is Essential

This critical component ensures your engine gets the right mix of air and fuel. The correct ratio is key for strong performance and fuel efficiency, while also cutting down emissions. The sensor constantly monitors exhaust gases to fine-tune engine operation in real time, helping your ride run at its best.

How It Works

Mounted on the exhaust stream, the sensor detects if the air/fuel mixture is too rich or too lean. It sends voltage signals to your car’s engine computer, which then adjusts fuel injection for optimal balance. This process keeps your engine smooth and responsive.

Problems from a Faulty Sensor

• Poor fuel mileage
• Rough engine idle
• Check engine light on
• Failed emissions test
• Possible engine misfire
