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.
Time Needed for Diagnosis: Value of Map1+ Value of Map2 + 22820 ms + 0 + Value of Map2 + 0 ms +
200000 ms + Value of Map3 + 0 ms + 200000 ms
Malfunction Indicator Light Illumination: Illuminates when malfunction occurs in 2 continuous driving cy-
cles.
