my gf bought a used S60 from a guy and now we are dealing with issu s that I can’t fix..We have two codes showing (P2407 and P2188). From what I’m hearing P2407 is common, but I not familiar with Volvo’s. I need help guys or someone who is able to repair this and won’t break me.. I live in Orange Beach, Al. Wanting help from someone who has a experienced this problem..
thanks so much!!

 

The P2407 is an evap system fault, the P2188 is running rich at idle. This combo suggests a vacuum leak - one likely cause is the "J tube" which is a hose back by the evap cannister. Also check to make sure your gas cap is sealing properly. There should be YouTube vids on the J tube fix, but you can also do a visual check on all the other vacuum lines. If nothing is obvious, try spraying around the lines with carb cleaner to see if some sucks in or you may need a shop to do a smoke test (a small machine pushes smoke into the vacuum lines to help find the leaks)
