To put it straight, your O2 sensor is your oxygen sensor. The O2 sensor is one of the main pieces of gear in the emission system of your motorized vehicle. It monitors the amount of oxygen in the vehicle’s exhaust stream, marking efficiency and ensuring that the catalytic converters are functioning properly.

Why Is It So Important?

The O2 sensor is an extremely important part of ensuring your vehicle is running smoothly and its performance is optimal.

If your O2 sensor isn’t working properly, it can result in poor fuel efficiency and end in serious damage to your engine. So keep an eye out.

How Do I Know If My Car’s O2 Sensor Needs to Be Replaced?

Good question. The only sure-fire way to know is with a diagnostic code reader, but there are warning signs. First, your check engine light might come on or you may notice a significant decrease in your vehicle’s fuel efficiency.

Or, your car may begin running roughly even after changing the plugs and wires. Lastly, another tell-tale sign is that your engine’s running rich and the plugs are fouled.

Where Is It Located?

Newer models will actually have two O2 sensors. The first is found on the exhaust pipe and closer to the engine, while the second is found closer to the muffler and catalytic converter.
