Have you ever wondered what's under your car's hood, and why a simple part like the oxygen sensor is so important?

We discuss the importance of a working oxygen sensor as well as some issues to be aware of below. When you need oxygen sensor or other auto repair in San Rafael, CA, visit Auto Repair Specialist.

What Does the Oxygen Sensor Do?

The oxygen sensor monitors the level of oxygen in the exhaust gases. Its primary function is to measure the air-fuel ratio and relay this information to the engine control module (ECM). This data allows the ECM to adjust the fuel injection for optimal combustion efficiency. Essentially, the oxygen sensor plays a pivotal role in ensuring the engine operates at the right mixture of air and fuel, contributing to fuel efficiency and minimizing harmful emissions.

Common Issues

There are a few issues that can arise when the oxygen sensor is damaged. Contamination is a prevalent problem; dirt and oil accumulation can lead to inaccurate readings. Another worry is that sensors degrade with time and become less precise. If your car is consuming too much fuel or the check engine light turns on, your oxygen sensor could be faulty. 

How To Keep Your Oxygen Sensor Functional

Regular maintenance is essential to keep your oxygen sensor in good working order. To keep your engine running smoothly, follow the service plan outlined in your owner's manual. Maintain a clean engine with regular oil changes to ensure a healthy oxygen sensor. Consider what you put in your tank: high-quality fuel lowers the likelihood of sensor contamination. Finally, if your gas mileage suddenly gets worse or the check engine light illuminates, have a professional inspect your vehicle.
