Answer 1

HI there

This code is sort of a catch all code for the evap system. Typically it means the computer knows there is a problem with the system, but doesn't know where the problem is. Several of the items need to be tested. A smoke test for leaks is probably the best place to start for this. Here is some more info on the code.
