When should I replace my O2 sensor?
Car manufacturers recommend replacing the O 2 sensor about every five years (one- and two-wire sensors) or 10 years (three- and four-wire sensors). However, silicon or carbon soot may cover an oxygen sensor due to a car repair or engine performance problems.
How often should you replace your O2 sensor?
Heated three and four-wire O2 sensors on mid-1980s through mid-1990s applications should be changed every 60,000 miles. And on 1996 and newer OBD II-equipped vehicles, the recommended replacement interval is 100,000 miles. A good oxygen sensor is essential for good fuel economy, emissions and performance.
Can I replace the O2 sensor myself?
When it comes to replacing a faulty O2 sensor, you have a couple options. Because sensors are plug-and-play, you may be able to do the replacement yourself . That said, sensors are not always easy to access. Even worse, sometimes the old sensors can seize in place, making them very difficult to remove.

What’s the difference between an oxygen sensor and an O2 sensor?
Some background info on difference of Oxygen Sensors and Air/Fuel Ratio Sensors. What distinguishes Air Fuel Ratio Sensors from regular O2 sensors is that the AFR Sensor is what is known as a wide range O2 sensor whereas the basic O2 sensor is a narrow range sensor.
