Increasing fuel efficiency and decreasing environmentally harmful exhaust emissions are two major, ongoing goals of the auto industry - goals which can be achieved by attaining the proper mix of fuel and oxygen. But how can you attain the right mix of fuel and air if your Volkswagen oxygen sensor is not working properly? What are oxygen sensors anyway and how does it works?
Oxygen sensors have been used in automotive exhaust systems for more than 25 years. Its job is to monitor the level of oxygen in the exhaust so an onboard computer can regulate the air-fuel mixture to reduce emissions. The oxygen sensor in other words is the final "feedback" sensor that lets the computer know how all its calculations are working out, by sending your car's computer data on the fuel/air ratio in the exhaust. The oxygen sensor sends the validation that everything else is working properly or isn't, whichever the case may be.
If your Volkswagen oxygen sensor malfunctions, it could no longer read the ratio, making your car perform poorly which may result to heavy fuel consumption. And eventually, this occurrence will lead to your engine performing inefficiently that will in turn cause the car's failure to pass emission tests. Do you see now why properly functioning Volkswagen oxygen sensor is important when it comes to your vehicle's fuel economy and exhaust emissions?
So checking for and possibly replacing a worn-out Volkswagen oxygen sensor is an important factor of every routine tune-up. By replacing your oxygen sensor on a regular basis, you'll get fuel economy and performance from your ride just like when you drove it off the showroom floor. Purchasing for new Volkswagen oxygen sensor is just easy. Volkswagen oxygen sensors are available in your local auto parts dealers and a wide array is offered in online auto parts stores.
How to Purchase the Right Volkswagen Oxygen Sensor
Do you wish to buy an oxygen sensor for your Volkswagen vehicle from an online or brick-and-mortar retailer? An online retailer is more affordable due to lower costs in maintaining a site versus maintaining a real store, but a shop enables you to acquire the part immediately off the shelf versus mail order shopping. With that said, you should get to know your replacement oxygen sensor up close and personal prior to purchasing it. Thankfully, this guide is here to help you every step of the way.
Considerations When Shopping for an Oxygen Sensor
Pick Between OEM versus Aftermarket Sensors:As a rule of thumb, you should as much as possible make sure that the sensor you 're buying is made by the same manufacturer of the stock sensor you lost (which usually means it 's made by Volkswagen or whoever company Volkswagen has partnered with to provide them with quality oxygen sensor parts). Maybe it 's made by Walker, Denso, Bosch, and so forth. Otherwise, check reviews and specs of aftermarket universal or vehicle-specific parts to make sure they 're at least OES.
Know What to Search for in an Oxygen Sensor: A high-performance oxygen sensor that matches or even exceeds the capabilities of your stock sensor should check the oxygen level of your exhaust in order to help determine the appropriate air and fuel mixture there then adjusting the level thusly for the sake of emissions reduction. It should also produce a voltage signal proportional to the oxygen inside the exhaust.
Look at the Packaging or Part Number:After receiving the package in question from an ecommerce mail order service, you should look at its packaging for more information that you can look up online. If the part lacks packaging, then take a look at the multiple digit part number imprinted on its barrel. That way, you can look up the origins of the sensor you 've received. For example, OEM Volkswagen oxygen sensors usually have a part number starting with USOS followed by a dash and four other numbers.
Make Sure That You 're Getting a Brand New Sensor: Check the remanufacturing origins of any used sensor you buy. Look for clues on the sensor in question to check how brand new it is. For example, all Bosch oxygen sensors have anti-seize on threads, so if there 's no anti-seize on the Bosch sensor, then it might be a used or even salvaged part from an old Volkswagen. Check for damage, minor dents, and chipping on the hex screw or the sensor in general as well.
Is Your Aftermarket Sensor Following the Emission Laws of Your State?Check with your state regulations for more details on whether a given sensor is following its rules or breaking them. Also, to err on the side of caution, buy only American-made oxygen sensors or their equivalents. It might get tricky since Volkswagen isn 't a U.S. company, but when it 's selling its cars to America, they come with sensors that follow EPA or (for example) CARB rules for emissions instead of European or German standards.
The Bottom Line
When making a price comparison chart of different websites and their oxygen sensor offerings for your Volkswagen, keep in mind that the prices go up and down based on the amount of sensors available in a given site 's inventory. Also, not all sensors sold online are made equal, so always pay attention to the specs, remanufacturing origins, manufacturers, and certification of the sensor you 're purchasing.
