Diagnostic Method
Compare the diagnostic value (fsobd) with the threshold value, and if a condition meeting the malfunction criteria listed below continues for 10 s X 3 time(s) or more, judge that there is a fault in the fuel system.
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 |
AMOUNT OF AIR - Map
| Amount of air (g (oz)/s) | 0 (0) | 3.2 (0.11) | 6.4 (0.23) | 9.6 (0.34) | 12.8 (0.45) | 16 (0.56) | 19.2 (0.68) |
| fsobdL1 (%) | 1.33 | 1.33 | 1.33 | 1.33 | 1.33 | 1.33 | 1.33 |
Time Needed for Diagnosis: 10 s X 3 time(s)
Malfunction Indicator Light Illumination: Illuminates when malfunction occurs in 2 continuous driving cycles.
