GENERAL DESCRIPTION
• Idling ignition
3. GENERAL DRIVING CYCLE
• If conditions are met, it is possible to detect the misfires from idling to high engine speed. However, in case
any engine load or breakage occurs, perform with the engine at idle.
• Perform the diagnosis continuously.

Diagnostic Trouble Code (DTC) Detecting Criteria
GENERAL DESCRIPTION
4. DIAGNOSTIC METHOD
When a misfire occurs, the engine speed will decrease and the crankshaft position speed will change. Cal-
culate the interval difference value (diagnostic value) from crankshaft position speed by the following formu-
la, and judge whether a misfire is occurring or not comparing the calculated result with judgment value. Count
the number of misfires, if the misfire ratio is higher during 1000 revs. or 200 revs., judge corresponding cyl-
inders as NG.
As shown in the following figure, pick a cylinder as the standard and name it omg 0. And the former crank-
shaft position speed is named omg 1, the second former crankshaft position speed is named omg 2, the third
is named omg 3, etc.
Diagnostic value calculation
(Calculate from angle speed) →
Misfire detection every single ignition
(Compare diagnostic value with judgment value) →
NG judgment (Misfire occurrence judg-
ment required by the law) (Compare
number of misfire with judgment value)
• 180° Interval Difference Method
• 360° Interval Difference Method
• 720° Interval Difference Method
• FTP 1.5 times misfire NG judgment
• Catalyst damage misfire NG judgment
