All ways seeing O2 sensor what ones to buy. I found this on the web. how to clean o2senor. so I thought why not give it a try as it costs nothing, soak senor in gasoline.
??? all you have to do is place sensor in small cup just cover sensor standing upright in gas up to the threads do not get the wires wet ,leave it to soak for 24 hours you will be amazed at the amount of crap that comes off it then let sensor dry reinstall in car clear code never have to pay for another sensor again it works I did it on sensors bank 2 upper and lower have not had a problem since give it a try before buying a new one jrb53 Merry Christmas to all

Hi jrb53,
Thanks for sharing.
Since oxygen sensors do fail, either the sensor or heater circuit, given the trouble of removing and installing some of them due to rust or their obstructed location in the vehicle, I've never tried just cleaning an O2S. But if the one you have codes for is easy to get to and remove, and the heater circuit tests good, it would certainly be worth a try.
But bear in mind that the sensor elements also become "tired" over time and can supply lazy or incorrect signals to the ECM, leading to suboptimal fueling.
Cheers,
Don
