That code means the comp is sensing flow when it shoudn't be purging. Possible a bad or stuck purge valve but it really should be checked out.....

Most DIYers don't have the tools required to properly check this system out......


I know....not much help but some faults are like that......No real easy way around it.........

To fully test the system you would need a scanner with bi-directional controls. Alot of the higher end AM scan tools didn't even have that ability until recently....

This may help a bit, some of it you could check with a vacuum pump........
