Diagnostic Method
WARNING: This page is about a different car, the 2012 Subaru Forester. However, it is still accessible from the selected car via links, so may be relevant.
- Abnormality Judgment
Judge as NG when the following conditions are established.
Judgment Value
JUDGMENT VALUE REFERENCE CHARTMalfunction Criteria Threshold Value Rich Main feedback learning value < -0.124 Sub feedback learning value < -0.043 When any one of the followings is established. - any one of the rich side misfire counters for each cylinder when in idling

Malfunction Indicator Light Illumination: Illuminates when malfunction occurs in 2 continuous driving cycles.
- Normality Judgment
Judge as OK and clear the NG if the following conditions are established.
