What does an Air/Fuel Ratio sensor do?

An Air/Fuel Ratio (A/F) sensor measures the amount of oxygen in your vehicle's exhaust gases. This data is sent to the engine control module (ECM) to help it adjust the fuel injection and maintain the ideal air-to-fuel ratio for efficient combustion.

How do I know if my A/F sensor needs replacing?

Common signs of a failing A/F sensor include a check engine light, rough idling, decreased fuel economy, poor engine performance, and increased emissions. A diagnostic scan can often pinpoint a faulty sensor.

Does this sensor come with the necessary hardware for installation?

This NGK Air/Fuel Ratio sensor is sold individually. It is recommended to refer to the manufacturer's installation instructions or consult a professional to determine if any additional hardware or sealants are required for your specific vehicle.
