Diagnostic Method

WARNING: This page is about a different variant/trim than selected.

Judge as NG when the following conditions are established.

JUDGMENT VALUE

Malfunction Criteria	Threshold Value
Rich
Main feedback learning value	< -0.01
Sub feedback learning value	< -0.03
When any one of the followings is established.
any one of the rich side misfire counters for each cylinder when in idling	> 20 time(s)
total of the rich side misfire counters for each cylinder when in idling	> 255 time(s)
any one of the rich side misfire counters for each cylinder when not in idling	> 20 time(s)
total of the rich side misfire counters for each cylinder when not in idling	> 255 time(s)
Lean
Main feedback learning value	> 0.01
Sub feedback learning value	< -0.012
When any one of the followings is established.
any one of the lean side misfire counters for each cylinder when in idling	> 20 time(s)
total of the lean side misfire counters for each cylinder when in idling	> 255 time(s)
any one of the lean side misfire counters for each cylinder when not in idling	> 20 time(s)
total of the lean side misfire counters for each cylinder when not in idling	> 255 time(s)

Time Needed for Diagnosis: 1000 engine revs.

Malfunction Indicator Light Illumination: Illuminates when malfunction occurs in 2 continuous driving cycles.

Judge as OK and clear the NG if the following conditions are established.
