Diagnostic Method
WARNING: This page is about a different car, the 2006 Subaru Outback. However, it is still accessible from the selected car via links, so may be relevant.
- Abnormality Judgment
Compare the diagnosed value (fsobd) with the threshold value, and if a condition where the malfunction criteria below are met continues for more than 50 seconds, judge that there is a fault in the fuel system.
Judgment Value
JUDGMENT VALUE REFERENCE CHART
| Malfunction Criteria | Threshold Value |
|---|---|
| fsobd = (sglmd - tglmda) + fan + flaf | ≤ fsobdR1 |
| In this case: sglmd = measured lambda, tglmda = target lambda, fan = main feedback compensation coefficient (every 64 milliseconds), flaf = main feedback learning compensation coefficient | Refer to ENABLE CONDITION REFERENCE CHART Map 4. fsobd R1 = rich side threshold value of fsobd |

Time Needed for Diagnosis: 10 seconds x 5 times
Malfunction Indicator Light Illumination: Illuminates when malfunction occurs in 2 continuous driving cycles.
- Normality Judgment
Judge as OK when the malfunction criteria below continues for 10 seconds.
