What is an Oxygen Sensor?

An oxygen sensor, commonly called an O2 sensor, is an instrument mounted in the vehicles exhaust system that continually oversees the oxygen content in the gases that leave the engine.

Before and after a catalytic converter are where the oxygen sensors are located. A vehicle can have up to 2 to 5 oxygen sensors, and occasionally, even more, depending on the vehicle.

How Does it Work?

The data from the oxygen sensor is used by the computer in the engine to assist in determining how much fuel is required so the engine will run as efficiently as possible. The sensor transmits this data by generating voltage once the sensor is heated. As the oxygen levels in the exhaust rise and fall the voltage will also rise and fall.

What are the Signs Related to a Faulty Oxygen Sensor?

A faulty oxygen sensor is one of the more typical causes for a check engine light to come on. Signs can include misfiring or hesitation from the engine, decreased fuel mileage, idling roughly or possibly stalling. A vehicle that fails an emissions test could be caused by a faulty oxygen sensor.

Is it Safe to Drive With a Problematic Oxygen Sensor?

A vehicle that has a faulty oxygen sensor may be driven safely until replacing the sensor. However, the vehicle won’t run as efficiently until the sensor is replaced.

Oxygen sensors will fail if they’re polluted with coolant, oil, silicone or other substances. When fluid pollution has caused an oxygen sensor to fail, the leak has to be fixed or the new sensor could also be damaged.

How Often are Oxygen Sensors Required to be Replaced?

On vehicles made since 1996, their oxygen sensors can go up to 100,000 miles or more prior to needing it to be replaced. That mileage will decrease on vehicles that are older.

How Can I Save Money on an Oxygen Sensor?

Don’t make the error of purchasing a replacement oxygen sensor from a mechanic or auto parts retailer. Find out the precise manufacturer part number for your vehicle, and then do a search online to find a much better price.

One other way to save money is not waiting for the sensor to fail. Check its function on regularly and have it replaced it if fuel efficiency decreases. This will reduce your overall average fuel costs each year. More vital, disregarding a faulty or failing oxygen sensor will ultimately cause the catalytic convertor to be damaged which is very costly to get replaced.
