Get the Best Priced GMC Yukon Oxygen Sensor

Driving an SUV comes with room, power, and efficiency, but the performance value is not there if an oxygen sensor fails. You have a lot to owe to each O2 sensor in your vehicle. Small and light, each sensor measures the level of oxygen in the exhaust so the proper air/fuel ratio can be determined by the computer. Oxygen sensors are important parts of the emissions control system. If one fails, it will impact environmental emissions and engine performance.

Symptoms of Oxygen Sensor Failure

If there is a failure at the 2004 GMC Yukon oxygen sensor location, there's a good chance you'll see the Check Engine light. The exact cause for this should be determined by a professional mechanic. It's often a sign the O2 sensor needs to be replaced. There can be performance issues as well. If the signal is thrown off by wear, corrosion, or build up, too much fuel may be added to the combustion chamber, reducing gas mileage and causing you to have to fill up more often. Rough engine idling is another sign of a bad oxygen sensor. The engine can also misfire because the O2 sensor helps control its timing and combustion intervals.

What Is an Oxygen Sensor?

Usually mounted in the exhaust manifold, it measures unburned oxygen. By monitoring how much oxygen is in the exhaust, the sensor helps the computer determine whether unburned fuel is getting past the combustion chamber or not. A voltage level indicates a rich or lean fuel mixture so the computer can adjust fuel injection accordingly. Automobiles have had O2 sensors since 1976, when the first one was used in a Volvo 240. Vehicles in California have had these sensors since 1980, and regulations were introduced in 1996 to include oxygen sensors, of the multiple ones, in all new vehicles.

When Should I Change My Oxygen Sensor?

The sensor can last from 60,000 to 90,000 miles if your vehicle was built less than 15 years ago. In vehicles built before that, replacements may be needed every 60,000 miles or less. It's not unheard of for a modern O2 sensor to go 100,000 miles; it's possible your 2003 GMC Yukon oxygen sensor can do the same. Today's sensors smaller, more reliable, and less susceptible to damage.

Cost of Oxygen Sensor Replacement

There are several variables when it comes to pricing O2 sensor replacement. You'd have to consider the 2000 Chevy Silverado O2 sensor location and, if your GMC Yukon sensor has failed, the make/model/year, your location, and mechanic's labor charges factor in. There are also taxes and possibly extra fees. Once you start to see bad O2 sensor symptoms, it's time to shop for a deal.
