If it is classified as a permanent code you can not clear it with any scanner........that's why they call it a permanent code. You can however get the Smog Center's computer to ignore it by driving 15-17 warm up cycle drives in Sport mode. Drive about 20 miles in each cycle. If you do the first drive early enough in the day for the car to completely cool down you can do another one late in the day. Otherwise it will take you a couple of weeks of driving to do all the cycles. Private message me if you have any questions.
