When it comes to oxygen sensors, Marsflex has you covered. With our high-quality Marsflex oxygen sensors available in our store, you can trust that you are getting a reliable and efficient product. It is important to note that heated oxygen sensors should be inspected or replaced every 60,000 miles, while unheated oxygen sensors should be checked every 30,000 miles.

If you are wondering whether you need to replace all sensors at once, it is recommended to replace O2 sensors in pairs. This is because replacing just one sensor can trigger a code for the other sensors due to differences in sensor activity. If you encounter difficulties removing the oxygen sensor, try using an O2 socket or a long ratchet for extra torque.

In the event that a fault code persists after replacing the oxygen sensor, there are several potential reasons including oxygen sensor circuit failure, rich or lean mixture, damage to the catalytic converter, or a faulty ECM. To avoid any incorrect purchases, carefully review the product description for vehicle fitment and compare part pictures to ensure compatibility.
