Abnormality Judgment
WARNING: This page is about a different variant/trim than selected.
Judge that the fuel system malfunction occurs when the time during completing the malfunction criteria below continues 50 seconds or more by comparing the diagnosed value (fsobd) with threshold value.
Judgment Value
JUDGMENT VALUE REFERENCE (ABNORMALITY)
| Malfunction Criteria | Threshold Value |
|---|---|
| fsobd = (sglmd - tglmda) + faf + flaf | >/= fsobdL 1 |
| where, | See Map 4 |
| sglmd = measured lambda | |
| tglmda = target lambda | fsobdL.1 = lean side threshold value of fsobd |
| faf = main feedback compensation coefficient (every 64 milliseconds) | |
| flaf = main feedback learning compensation coefficient |
