Oxygen Sensors

Ensure optimum engine performance through quality oxygen sensor repair and replacement from Saul’s Autotek.

Serving the Centennial State Since 1989

The oxygen sensor is the component responsible for measuring the amount of unburned oxygen in the exhaust system.

It then relays the information to the electronic control unit, most commonly called the ECU, to help figure out the best air-fuel mixture for the best engine performance.

When your vehicle’s oxygen sensor malfunctions or gets damaged, most essential engine functions will be disrupted. These engine functions include combustion interval, air-fuel ratio, and engine timing. It’s for this reason that it’s essential to keep your oxygen sensor working properly.

At Saul’s Autotek, we have a team of ASE-certified mechanics who can help you keep your oxygen sensor in optimal condition. We have over three decades of experience in the automotive service industry. Our experience gives you the assurance that we have the required training to service your oxygen sensor.

Signs Your Oxygen Sensor Needs Servicing

Since the oxygen sensor is a vital component, it’s essential that you know the signs it needs servicing. Here are some common ones to look out for:
Dashboard showing car's high mileage

1. Illuminated Check Engine Light

Although your vehicle’s check engine light may indicate various problems, one of the most common triggers is a malfunctioning oxygen sensor, especially if you drive a high-mileage vehicle.
Fuel gauge that reads full tank

2. Reduced Gas Mileage

When your oxygen sensor fails, your vehicle may compensate by using more fuel. This not only leads to poor fuel economy but also causes several dire effects, such as rotten egg smells, increased tailpipe emissions, and overheated catalytic converters.
Old and rusty engine parts due to poor car maintenance

3. Poor Engine Performance

As mentioned, a failed oxygen sensor disrupts essential engine functions. If you notice that your engine isn’t working properly, don’t delay calling professional mechanics. It’s less costly to have your oxygen sensor serviced than replace your engine.

4. Rough Idling

The normal RPM for an idle vehicle is under 1,000. If your RPM reaches 2,000 to 3,000, however, you’re dealing with rough idling. This can be due to a bad oxygen sensor that causes the engine timing to be more difficult to control.
Vehicle's exhaust emission

5. Failed Emission Test

With the oxygen sensor located in the exhaust system’s manifold, it’s able to help with emissions control. You might discover that it’s damaged when your vehicle fails the emissions test.

Why Invest in Cabin Air Filter Replacement

Clean and functional cabin air filters are essential in maintaining fresh and healthy air inside your vehicle. Neglecting to replace filters can negatively affect your vehicle and lead to serious consequences. Here’s why it’s vital to have your cabin air filters replaced:

If your filter is clogged, your engine needs to work harder to power your vehicle’s heating and cooling systems. Clean cabin air filters put less strain on your engine, resulting in less wear and tear and better fuel efficiency.

Clean cabin air filters can help your modern vehicles accelerate faster. When clean air enters your vehicle’s engine, it encourages improved efficiency, which creates mоrе horsepower аnd torque.

Regularly replacing your cabin air filters significantly reduces the pollutants that you inhale. They act as a barrier between the outdoor air and the inside of your vehicle, and they can prevent most of the smog, smoke, and ash from entering.
