Would like the information on the criteria on which P0431 will clear on its own (example: three drive cycle with no repeat failures will shut off light). I have all rediness monitors complete and would rather not clear the code and reset all the monitors.

That is a continuous monitor code. It only clears itself if the convertor is working properly based on what the O2 sensors see.
