Subaru 22641AA720: The Heartbeat of Your Engine

As a car enthusiast or a vehicle owner, you are likely to know the importance of keeping your engine in optimal condition. One essential component that ensures this is the Subaru 22641AA720, also known as the A/F Ratio Sensor or Oxygen Sensor.

Why You Need The A/F Ratio Sensor

The A/F Ratio Sensor plays a stellar role in maintaining the performance of your vehicle's engine. This part measures the amount of oxygen present in your car's exhaust gas. Subsequently, it modifies the air-fuel mixture ratio by sending signals to the engine control unit (ECU). By adjusting the fuel injection, combustion efficiency is optimized, which results in improved fuel economy, enhanced engine performance, and reduced emissions.

How It Works

When functioning correctly, the A/F Ratio Sensor cycles once every second and produces a voltage signal that varies from about 0.1 to 0.9 Volts. This voltage signal is sent directly to the ECU, which interprets it and ensures the proper air-fuel mixture for optimal combustion.

The Impact of a Faulty A/F Ratio Sensor

Should the A/F Ratio Sensor break or malfunction, the repercussions could be significant. Your vehicle may experience poor fuel economy, irregular engine performance, and increased emissions. In the long run, it can result in costly damage to essential components like the catalytic converter.

Compatibility

For those who own a Subaru, it's important to note that the Subaru 22641AA720 SEN AY-A/F RATIO is compatible with the following car models:

• Wrx/Levorg
• Wrx

Ensure your car maintains its peak performance by replacing faulty parts promptly. Remember, the A/F Ratio Sensor plays a crucial role in keeping your vehicle's engine running at its best.
