*: If Purge VSV is stuck open, air is sucked in from Purge VSV, and the air fuel ratio becomes Lean and stores P017100.

If any EVAP system DTCs are output, the malfunctioning area can be determined using the table below.

NOTE:

If the reference pressure difference between the first and second checks is more than the specification, all the DTCs relating to the reference pressure (P043E00, P043F00, P24007E, P24007F and P24187E) will all be stored.
