Oxygen Sensor Replacement: Boost Your Subaru’s Performance ?

Why Is This Part Essential?

The oxygen sensor is a crucial piece of your vehicle’s emissions system. It monitors the air-fuel mixture going into your engine, sending real-time feedback to the ECU for optimum combustion. Having this part in good working order ensures your engine runs efficiently, saving fuel and reducing harmful emissions.

How Does It Work?

Located in the exhaust stream, this sensor precisely reads oxygen levels in gases leaving the engine. The data is used by the ECU to adjust fuel input, helping maintain the correct air-fuel ratio. This process results in better engine performance, smoother acceleration, and lower emissions.

Risks of a Broken Sensor

• Check engine light comes on
• Increased fuel consumption
• Unstable idling and rough engine performance
• Failed emission tests
