Oxygen Sensor: Essential Emissions Control Component

Why You Need This Sensor

This sensor plays a critical role in reducing your car’s fuel consumption and keeping emissions low. It monitors oxygen levels in the exhaust gases, sending vital data to your vehicle’s engine control unit (ECU). The ECU uses this information to balance fuel and air mixture, ensuring efficient combustion, better performance, and compliance with environmental standards.

How This Part Works

Located in the exhaust manifold, the component continuously checks the amount of oxygen exiting the engine. The sensor generates a voltage signal based on oxygen content. The ECU interprets this signal and adjusts fuel injection timing and amount, keeping the engine running smoothly and efficiently.

What Happens If It Fails?

• Check engine light appears 🚨
• Reduced fuel efficiency ⛽
• Rough engine idle and stalling
• Higher emissions, failed inspections 🌫️
• Poor acceleration and loss of power
