GENERAL DESCRIPTION
720° Interval Difference Method
FTP 1.5 times misfire (Misfire occurrence level which influences exhaust gas)
Time Needed for Diagnosis: 1000 engine revs.
Malfunction Indicator Light Illumination: Illuminates when malfunctions occur in 2 continuous driving cy-
cles.
Catalyst damage misfire (Misfire occurrence level damaging catalyst)
Diagnostic value domg 720 = (omg 1 – omg 0) – (omg 7 – omg 6)
Misfire judgment domg 720 > Judgment value → Judge as misfire
Judgment Value (Judge that malfunction occurs when the misfire ratio is high in 1000 engine revs.)
Malfunction Criteria Threshold Value
FTP emission judgment value > 1.0 % in 1000 revs.
