Diagnostic Method
Compare the diagnostic value (fsobd) with the threshold value, and if a condition meeting the malfunction criteria below continues for 10 s x 3 time(s) or more, judge that there is a fault in the fuel system.
Judgment Value
JUDGMENT VALUE SPECIFICATION
| Malfunction Criteria | Threshold Value |
|---|---|
| fsobd = (sglmd - tglmda) + faf + flaf | ≥ Value from Map |
| In this case: sglmd = measured lambda tglmda = target lambda faf = main feedback compensation coefficient (every 64 milliseconds) flaf = main feedback learning compensation coefficient |
