Chevrolet or Chevy is an American automobile division of General Motors (GM), and it’s one of the most successful automobile brands in the United States. It has a reputation for quality, safety, and innovation, ensuring that every Chevrolet vehicle is reliable and durable. However, similar to all other automobiles, age and regular use can cause your Chevrolet car parts to fail. One component that you should specifically look out for is the Chevrolet oxygen sensor. When this part starts acting up, make sure to address the issue immediately.

All General Motors O2 sensors or oxygen sensors are manufactured either here in the United States or made by General Motors suppliers from around the globe. In the United States alone, this automaker giant has 120 facilities across different states including assembly plants, components plants, battery plants, stamping plants, propulsion plants, parts distribution centers, and engineering campuses.

Original Equipment Manufacturer or OEM Chevrolet parts are manufactured by the same company or brand that produced the stock parts in your vehicle. This can either be Chevy or one of its suppliers. More often than not, OEM Chevrolet parts are more expensive than their aftermarket counterparts. And when it comes to quality and fit, OEM components are guaranteed to be suitable replacements for your vehicle’s worn out parts.

OE replacement or aftermarket Chevrolet parts, on the other hand, are not made by Chevy’s official suppliers. They are manufactured by third-party companies that decide everything about the OE parts including the design and materials used.

The aftermarket car parts industry has already caught up with OEM manufacturers when it comes to design and quality. In fact, some aftermarket brands can produce replacement car parts that perform better than OEM components. That said, it practically makes no difference if you get an aftermarket Chevrolet oxygen sensor as a replacement for your faulty part.

The price of a replacement Chevrolet oxygen sensor depends on several factors including the brand, quantity, and materials used. Your Chevy’s year and model are usually taken into account as well. On CarParts.com, one oxygen sensor can cost anywhere between $3 and $350. The price of replacement oxygen sensors that are sold in sets of two to four, on the other hand, ranges from $20 up to $280. Also, each oxygen sensor is typically offered with a warranty from the brand.

The built-in vehicle selector on our website can aid you in finding the right oxygen sensor for your ride. If you are looking for a Chevrolet Cruze oxygen sensor, just plug in its year, make, and model in the vehicle selector so that you can have a customized set of options. Once all the Chevrolet Cruze oxygen sensors appear in the search results, you can filter them further by price range, location, brand, fit, series, and quantity sold.

Your Chevy oxygen sensor is a sensitive automotive part that serves to help your combustion system work at its most efficient, while helping to see to it that less pollutants escape into the air we breathe. Located in the exhaust system, your Chevy oxygen sensor measures the amount of oxygen in the exhaust gasses as they leave the combustion system. If the oxygen level is not at the right level, that lets the Chevy oxygen sensor know that the burn is not happening as efficiently as it should, causing the Chevy oxygen sensor to signal the main computer of the vehicle that the air-to-fuel ratio needs to be adjusted. When your Chevy oxygen sensor starts to move towards failure, you're likely to notice a variety of symptoms that relate to improper fuel burn, such poor fuel mileage, an excess of emissions, power loss and hesitation. If your Chevy oxygen sensor fails and is not replaced promptly, you place your catalytic converter at risk of failure, as well, as it can be overwhelmed by the excessive emissions that an improper or incomplete burn can produce. Fortunately, there's no need for procrastination, as this is not a difficult replacement to perform and, when you shop with us, you'll be able to find an affordable and great quality Chevy oxygen sensor replacement for your vehicle year and model in our online catalog, which is home to numerous aftermarket parts and accessories. Ordering is always safe and convenient, and we offer two easy ways to place your order. You can use our securely encrypted site to place your order or you can order your Chevy oxygen sensor replacement via our toll-free telephone number.

The oxygen sensor plays a big role in the fuel control feedback loop of the vehicle. It measures the amount of unburned oxygen in the exhaust and sends a voltage signal to an engine computer to help it fine-tune the fuel mixture. But as the sensor ages, some of its capabilities are compromised. With contaminants gathering on the sensor tip over time, the sensor may not be able to create voltage easily. When lead, silicone, oil ash, sulfur, and fuel additives find their way through the oxygen sensor, the unit may fail after some time. Exposure to water, road salt, and dirt can also damage the sensor. As the sensor deteriorates and turns sluggish, the engine computer can't make the necessary fuel mixture adjustments to keep emissions within limits. A faulty sensor will mess up the feedback control system, forcing it into an open loop with fixed, rich fuel mixture that will cause fuel use and emissions to rise unexpectedly. In a study, it is said that a good number of vehicles don't pass the emissions tests due to a bad oxygen sensor. It is often overlooked as a cause of drivability problems. To keep the Chevrolet oxygen sensor in good working condition, here are some tips:

• Perform oxygen sensor checks.

The oxygen sensor may short-circuit. The circuit may also open or go out of range. When it does, this usually leads to a fault code that will turn the service engine lamp on. It will then help if you have a tool for deciphering trouble codes or know how to read diagnostic trouble codes to pinpoint the problem and make it easy to trace the underlying cause of a drivability issue. On OBDII-equipped vehicles, a scan tool graphing feature may be used to assess or monitor the oxygen sensor performance. It will also help if you can read the sensor's output to find out any irregularity. There are times, however, when a degraded oxygen sensor may not set a fault code but may cause emissions and fuel consumption to spike, symptoms of impending sensor failure. If fuel consumption and emissions are too high, you may have to check the sensor and perform other tests on fuel pressure and delivery, engine compression and vacuum, and the ignition system to diagnose the issue. By checking the oxygen sensor, you can figure out whether it needs to be cleaned before it becomes sluggish or unresponsive or has to be replaced altogether.

• Clean the oxygen sensor.

Oil, coolant, and other elements may get into the oxygen sensor. Cleaning the sensor will help eliminate unwanted elements and extend the life of the sensor while also making the sensor more responsive and effective in monitoring the level of unburned oxygen. This helps prevent inefficient combustion and improves performance. When cleaning the sensor, spraying it with WD-40 and leaving this on for a few minutes will lubricate the sensor and make it easier to remove it. Using a safe container, the sensor must be soaked in gasoline overnight. Store this in a dry, cool area. If there are still dirt and sediment on the sensor, use a soft-bristled brush to scrub it gently. Remove excess gas on the sensor by wiping it off with a paper towel and let it dry fully before re-attaching it.

• Know when to replace the oxygen sensor.

Check the manufacturer specifications to know the average lifespan of the oxygen sensor and when this should be replaced. Newer OBDII-equipped vehicles, for instance, require replacement every 100,000 miles. If the sensor is already sluggish and is causing a spike in fuel consumption and emissions, along with drivability issues, this should be replaced as soon as possible not only to restore function but also to protect the converter.
