Judge as NG when the following conditions are established.
Judgment 2
Judge whether the reference pressure is within the normal range, and detect the vacuum pump and orifice malfunctions. Judge the vacuum pump performance stability.
Judge as NG when the following conditions are established.
Judgment 3
Judge the presence of evaporative emission system leak.
Judge as NG when the following conditions are established.
