Diagnostic Trouble Code (DTC) Detecting Criteria
GENERAL DESCRIPTION
Mode E: (Evaporation occurrence amount calculation)
Calculate the change of tank pressure with the time evpdset to judge as NG/OK according to the value of P1.
(ambiguous determination acceptable).
• Abnormality Judgement
Judge as NG when the following conditions are established.
