[QUOTE="Dirty Dog, post: 463971, member: 24042"] Permanent codes stay until the computer decides the condition no longer applies. That could require a certain number of cold starts, or a certain number of miles, or whatever. If you have a permanent code and no current or pending codes, then I wouldn't worry about it. I'd drive it for a week or two and then rescan it to see if the permanent code has cleared. [/QUOTE]
