Installed the WOT defeat plug a couple of years ago and now due the 5 year coolant change at the dealer. Is it better to leave the WOT defeat plug in place (concerned they may remove it and throw it away and install a new sensor) or take out the defeat plug and reinstall the old sensor (concerned this might cause a latched code that I will have to pay for in addition to the coolant change)? Has anyone reinstalled the old sensor before dealer servicing without any problems? Any thoughts on the best option?

Mike
