## Questions & Answers

**Q: What is the life expectancy of an oxygen sensor?**
A: Heated oxygen sensors should be checked or replaced every 60,000 miles, while unheated oxygen sensors should be checked or replaced every 30,000 miles

**Q: Do I need to replace all of the sensors at once?**
A: It is best to replace O2 sensors in pairs. Because, replacing one sensor will cause the ECU to set a code for the other sensors. This is because the new sensor switching activity is much faster than that of the older aged sensors

**Q: The oxygen sensor will not come out.**
A: If you are using an open end wrench, try an O2 socket. If this fails, try a long ratchet or breaker bar in conjunction with your socket to generate more torque. After the sensor is removed, be sure to use a thread cleaner to clean up the bung threads

**Q: Why does the fault code still exist after replacing the oxygen sensor?**
A: 1 Oxygen sensor circuit failure

**Q: Will this oxygen sensor work with my vehicle?**
A: Marsflex oxygen sensor is consistent with OEM, please refer to the page information for compatibility information. You can check 'Amazon confirmed it' for confirmation, or provide us with your vehicle information and we will confirm it for you.
