Oxygen Sensor Replacement Service at Shingle Springs Subaru Service Center in Shingle Springs, CA

January 17, 2019

Often shortened to "O2 sensor," the oxygen sensors in your car play a critical role in the smooth operation of the engine. Modern cars are computer-controlled, and they rely on information from the oxygen sensors to know just how well the engine is running. O2 sensors can detect problems, like a lean or rich air/fuel mixture, so the system can compensate. The result of all this technology is an engine that runs smoothly and efficiently in all kinds of conditions and with very little maintenance!

Having said that, you should know that O2 sensors can go bad. They can stop working after being fouled with carbon build up over time; they can be damaged by fluid leaks; sometimes, they simply go bad due to age. If your engine has started running roughly, using more fuel or not giving you as much power as you expect, a bad O2 sensor just might be to blame. Let us install a new one at the Shingle Springs Subaru service department so your car runs like it should.

What are the Symptoms of a Bad O2 Sensor?

A bad oxygen sensor can often lead to a rich air/fuel mixture in your engine. That means more fuel is added to the engine than can be efficiently burned. Unburnt gasoline vapors will be sent through the exhaust, which can often be detected by smell. A rotten egg odor is a sure-fire sign that your vehicle needs service to fix the air/fuel ratio. You're also likely to notice poor fuel economy, a rough idle, black exhaust fumes and the check engine light may also turn on.

How Long do Oxygen Sensors Last?

On a modern car, the oxygen sensors typically last anywhere from 60,000-100,000 miles before needing to be replaced. They can go bad faster if they become fouled by engine oil, coolant or gasoline. If your car has been running poorly, no matter how many miles are on it, checking the O2 sensors is always a good place to start.
