Essential Oxygen Sensor for Efficient Engine Performance

Why Do You Need This Part

This sensor is a vital component in your vehicle’s exhaust system. It monitors the oxygen levels in the exhaust gases and sends this data to the engine control unit (ECU). The ECU uses these readings to adjust the air-fuel mixture, ensuring your engine runs smoothly and efficiently.

How Does It Work

The sensor sits in the exhaust stream and detects the ratio of oxygen to fuel. It relays information continuously, allowing real-time adjustments to fuel injection. This process helps your car achieve optimal fuel economy and lower emissions.

What Happens If It Breaks

• Poor fuel efficiency
• Rough engine running or stalling
• Increased emissions
• Illuminated check engine light
• Failed emissions test
