Oxygen Sensor Replacement

oxygen sensor replacementThe oxygen sensor was developed in the early 1980’s, and is an vital component of your vehicle’s emission control system. Resembling a spark plug, the sensor is installed so that it sits directly in the car’s exhaust stream, where it measures the exhaust and determines the amount of oxygen present, which will then help the sensor determine necessary adjustments the engine can make to the amount of fuel being used in the engine in an effort to run at maximum efficiency. If you need an oxygen sensor replacement in Knoxville, TN or the surrounding areas, give People’s Choice Auto Repair a call at .

O2 Sensor Failure

There are a number of reasons that an oxygen sensor can fail. If the car’s engine is running efficiently and is properly maintained, an oxygen sensor can last for 100,000 miles, but can fail prematurely due to gasoline additives, oil from worn engines, and combustion byproducts such as sulfur & lead. This contamination can cause the sensor to lose its ability to produce the necessary voltage for sending a proper signal.

Using a different octane of fuel than what is recommended for your vehicle’s engine, or using low-quality gasoline can also lead to failure of your oxygen sensor. If regular maintenance of your engine is neglected, the likelihood for incomplete fuel combustion is increased, which in turn leads to your oxygen sensor failing faster than it otherwise would.

Signs You Need an Oxygen Sensor Replacement

A fouled oxygen sensor will usually trigger your check engine light to flash. This is the most recognizable failure, and unfortunately the only real recognizable one. A failing oxygen sensor will cause a gradual decrease in gas mileage, but this is typically not notice unless one regularly keeps track of their MPG (Miles Per Gallon).
