Diagnostic Method
WARNING: This page is about a different variant/trim than selected.
- Abnormality Judgment
Compare the diagnosed value (fsobd) with the threshold value, and if a condition meeting the malfunction criteria below continues for 10 s x 5 time(s) or more, judge that there is a fault in the fuel system.
JUDGMENT VALUE CHART
| Malfunction Criteria | Threshold Value |
|---|---|
| fsobd = (sglmd - tglmda) + faf + flaf In this case: sglmd = measured lambda tglmda = target lambda faf = Main feedback compensation coefficient (every 64 ms) flaf = main feedback learning compensation coefficient |
