I just bought the tool to do mine. I'd let you borrow it, but they are so cheap you might as well buy one. Getting ready to clean out my tube and do a bunch of other little repairs. Best of luck with your codes. BTW, are there any symptoms besides the codes popping up? loss of performance or anything weird?

Here's a link to the tool:
