The Bentley manual describes how they clear themselves if the error conditions don't repeat for the next X drive cycles. I have got a couple that show up from time to time, and then they clear themselves. Since I have been to FL they haven't shown up, until the other day
I haven't even read them yet;; I think it is one of the secondary O2 sensors. I have all the troubleshooting steps, but just haven't fooled with it since the car is running great, and they haven't been on (until the other day, sigh...)
