Air-Fuel Ratio Monitoring Sensor ?

Why This Sensor Is Essential

This precision sensor plays a crucial role in your engine’s performance by continuously monitoring the mixture of air and fuel in the exhaust. It sends real-time signals to the engine control unit (ECU) to help optimize combustion, reducing emissions and improving fuel efficiency. Modern vehicles rely on this sensor to keep engine function smooth and environmentally friendly.

How The Sensor Works

Installed in the exhaust manifold, the sensor detects the level of oxygen in the exhaust gases. It generates a voltage based on the air-fuel mix, allowing the ECU to adjust fuel injection for the perfect balance. This process ensures effective combustion and prevents damage from running too rich or too lean.

What If the Sensor Is Faulty?

When this sensor fails, you might notice poor fuel economy, rough idling, engine misfires, or even a check engine light. Over time, ignoring a bad sensor can lead to higher emissions and potential damage to the catalytic converter, resulting in costly repairs.
