Question about 1999 GMC Yukon
I got a code P 1416 tells me to replace the air check valve however wanted to know if I can clean them and then rest light and see if it turns off for good
If you get it apart then you may be able to clean it . A good carbon dissolver may do the trick but I would not waste my time as it may not seal properly when you have finished.. It may have a broken spring inside that you will not be able to replace as well.
