Essential Emissions Component: Oxygen Sensor ?⚡

The oxygen sensor is a critical part of your car's exhaust system. This sensor monitors oxygen levels in the exhaust gases, helping your engine control module (ECM) adjust the air-fuel mixture for maximum efficiency and reduced emissions. Proper fuel combustion ensures better mileage, smoother performance, and compliance with emission standards.

How This Sensor Works

Mounted in the exhaust manifold, the sensor continuously detects oxygen content in exhaust fumes. It sends voltage signals to the ECM. Based on these signals, the ECM fine-tunes the ratio of fuel and air entering the engine, optimizing both power output and fuel economy.

What Happens If It Fails?

• Poor fuel economy
• Engine hesitation or rough running
• Check Engine Light illumination
• Increased emissions, possible test failure

If this sensor is broken, the ECM receives incorrect data, causing rich or lean fuel mixtures that hurt performance and the environment.
