Rear Oxygen Sensor: Crucial for Engine Performance

Why Is This Part Needed

The rear oxygen sensor is critical in measuring your car’s exhaust gases. This data allows the engine's computer to adjust the air-fuel mixture for optimal combustion. Keeping emissions low and efficiency high, this sensor helps you pass emission tests and saves fuel.

How Does It Work

Positioned downstream in the exhaust system, the sensor continually detects oxygen levels after the catalytic converter. Its readings inform your vehicle’s ECU, ensuring your engine remains within environmental standards and runs smoothly.

Consequences of a Broken Sensor

• Check engine light appears
• Engine performance drops
• Poor fuel economy
• Higher emissions
• Catalytic converter damage risk
