Mode E (Measurement of reference pressure for judgment)
Judgment 1
Purpose: Judge the reference pressure stability.
Judge as NG when the following conditions are established.
Judgment 2
Purpose: 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
Purpose: Judge the presence of evaporative emission system leak.
Judge as NG when the following conditions are established.

Time needed for diagnosis: 23 min
At next engine start, confirm whether the enable conditions are satisfied even though refueling has been done during soaking, and determine the malfunction.
Malfunction indicator light illumination: Illuminates when malfunction occurs in 2 continuous driving cycles.
