Oxygen Sensor: Ensuring Your Engine Gets the Right Mixture

Oxygen Sensor: What It Is and Why It Matters at Meineke in Northbrook

When your fuel efficiency drops on Dundee Road or your check engine light glows while heading to the park for some baseball, the issue may be your oxygen sensor. Since the oxygen sensor monitors exhaust gases, it helps your engine adjust the air-fuel mix. Because Northbrook drivers depend on their vehicles for commutes, errands, and trips into Chicago, a healthy oxygen sensor is essential for performance.

At Meineke in Northbrook, our ASE-certified mechanics test, repair, and replace oxygen sensors with precision. So, in this post, you’ll learn what the oxygen sensor is, how it works, why it matters, how to maintain it, and when to visit your trusted Meineke shop in Northbrook.

So, What the Oxygen Sensor Is and How It Works

The oxygen sensor sits in the exhaust system. Since it measures oxygen levels in the exhaust, it sends data to the engine control module. Because the ECM adjusts fuel injection based on this data, the engine maintains efficiency. As a result, the oxygen sensor keeps performance and emissions in balance.

So, Why the Oxygen Sensor Is Important

Although it’s small, the oxygen sensor has a big role.

• Since it optimizes fuel use, it improves fuel economy.

• Because it reduces emissions, it helps protect the environment.

• As a result, it prevents damage to the catalytic converter.

• That’s why oxygen sensor care is vital for Northbrook drivers.

So, How to Maintain the Oxygen Sensor

Good habits protect your oxygen sensor.

• Since poor fuel damages sensors, always use quality gas.

• Because exhaust leaks affect readings, repair them quickly.

• For this reason, keep up with tune-ups to avoid running rich fuel mixtures.

• Additionally, replace the sensor as recommended, usually every 60,000–90,000 miles.
