What Is an O2 Sensor?
An O2 sensor, also known as “an oxygen sensor,” is part of your vehicle's exhaust system. The O2 sensors monitor the level of oxygen in the exhaust to adjust the air to fuel ratio for optimal efficiency. As you may know, your vehicle's engine contains an oxygen and fuel mixture that, if present in the correct ratios, ensures the best fuel economy for your vehicle. We at Johnson Automotive & Electric in Eureka can go over these ratios with you if you'd like. If there is too much or too little oxygen in your vehicle's engine, the oxygen sensor will send a signal to the engine's computer and more or less fuel will enter the engine to restore the correct ratio.
To prevent engine damage and damage to the catalytic converter as well as keep your vehicle's emissions systems in check, it is important that your O2 sensor work properly; if the fuel-to-air ratio is not ideal, it will compromise the fuel economy of your vehicle. Johnson Automotive & Electric has performed hundreds of O2 sensor services for residents of Eureka, CA, Arcata, CA, Fortuna, CA, Garberville, CA, McKinleyville, CA, and beyond, so you can trust us with your vehicle. In general, newer oxygen sensors can last for up to 100,000 miles or more if they are maintained regularly. We at Johnson Automotive & Electric will take a look at your O2 sensors as part of your vehicle's maintenance.
How Do I know If My Vehicle Needs an O2 Sensor Replacement?
It is imperative to note that although your vehicle may appear to need an oxygen sensor service, the real problem may be faulty spark plugs. If the spark plugs in your vehicle are misfiring, there will be excess oxygen in your vehicle's exhaust because the spark plugs are not burning the fuel and air. Our technicians at Johnson Automotive & Electric will check for that issue when you bring your vehicle in.
Whether you drive a Audi, Volkswagen, BMW, Mini Cooper, or any other vehicle, the signs of a faulty O2 sensor are universal. In most cases, your O2 sensor can be repaired. However, you may need a sensor replacement if the oxygen sensor fails. We at Johnson Automotive & Electric in Humboldt County can guide you through what your vehicle needs. Here are some warning signs that your O2 sensor needs repairs or a sensor replacement:
- Your check engine light turns on: This light could turn on for a variety of reasons, and we at Johnson Automotive & Electric can give you an exact diagnosis. However, if your check engine light turns on and you are experiencing the following symptoms, your vehicle probably needs an O2 sensor service.
- You are getting less miles per gallon: If the O2 control systems are not working properly, the fuel-to-air ratio will be thrown off and will compromise the efficiency of your vehicle. Not only will you end up spending more money on gas and your vehicle will have a more negative environmental impact if you do not get this issue resolved, but you also run the risk of not passing a vehicle emissions test when the time comes.
- Your engine misfires and/or you experience a rough engine idle: Because the O2 sensor controls engine timing and the all-important fuel-to-air ratio, a bad sensor can disrupt these engine functions
