I have a question, can a swapped rear o2 sensor from bank 1 to bank 2 and the other from bank 2 to bank 1? Because a misfire. I've been having a misfire on bank 1 on heavy acceleration and don't know if rear o2 sensors are reversed.

Yes, you can. An o2 sensor is just an o2 sensor so the only real difference between them is the fitment. So you have a sensor for just the left front and that may be just because it is a tight space and the may not fit.

However, they are only measuring oxygen content so there is no difference with the actual sensors.

Here is a guide that will help with testing o2 sensors if you would like to do this as well:

However, if you have a misfire, this guide will walk you through some other things as well but swapping the sensors to see if the misfire changed banks is a good idea.

Please see the info below on each of the sensors and let us know if you have questions and what you find.

Thanks
