What is an oxygen sensor?
The oxygen sensor, sometimes called an O2 sensor, is a device mounted in the exhaust system that constantly monitors the oxygen content in the gases that exit the engine.
Oxygen sensors are located before and after the catalytic converter. A vehicle may have two to five oxygen sensors, and sometimes even more.
How does the oxygen sensor work?
The information from the oxygen sensor is used by the engine's computer to help determine how much fuel is needed so that the engine will run efficiently. The sensor sends this information by producing voltage when the sensor is heated. The voltage rises and falls as oxygen levels in the exhaust rise and fall.
What are the symptoms related to a bad oxygen sensor?
A faulty oxygen sensor is one of the most common causes of a check engine light. Symptoms may include a decrease in fuel mileage, hesitation or misfiring from the engine, rough idling or even stalling. A faulty sensor may cause the vehicle to fail an emissions test.
Can I drive with a oxygen sensor problem?
A vehicle that has a bad oxygen sensor can be driven safely until the sensor can be replaced. But the car will not run as well until the repair is made.
Oxygen sensors can fail if they are contaminated with oil, coolant or silicone. If fluid contamination has caused an oxygen sensor to fail, the leak must be fixed or the new sensor may be ruined too.
How often do oxygen sensors need to be replaced?
On cars manufactured since 1996, oxygen sensors can go 100,000 or more before needing to be replaced. That mileage decreases on older cars.
How are oxygen sensor issues diagnosed?
A faulty oxygen sensor is usually diagnosed by a technician using a diagnostic scan tool. The sensors are arranged in banks, usually on the right and left sides of the engine, and the scan tool alerts a technician to which sensor is not working properly.
How is a oxygen sensor replaced?
Once the bad sensor has been found, the vehicle typically must be lifted to provide access to the exhaust system. The bad sensor is disconnected from the wiring harness and replaced.
RepairPal recommendations for oxygen sensor issues
We recommend using only high-quality OEM oxygen sensors as opposed to cheaper replacements that may not be recognized by a vehicle's computer.
Can I replace the oxygen sensor myself?
This repair doesn't require a lot of tools, but it still can be tricky. You'll need a scan tool to determine which oxygen sensor needs to be replaced, the ability to safely lift and support the vehicle, and often an oxyacetylene or propane torch to aid in removal of the oxygen sensor.
If you're not comfortable with these aspects, it's best to take the car to a repair shop for a sensor replacement.
