Diagnostic Method
WARNING: This page is about a different variant/trim than selected.
Judge that the malfunction occurred in fuel system when the malfunction criteria are completed for 50 seconds or more by comparing the diagnostic value (fsobd) with threshold value.
Judgment Value
JUDGMENT VALUE
| Malfunction Criteria | Threshold Value |
|---|---|
| fsobd = aflmd + lambda + kblrc | ≥ fsobdL1 |
| aflmd = measured lambda | See Map 2 |
| lambda = short term fuel trim | fsobdL1 = lean side |
| kblrc = long term fuel trim | threshold value of fsobd |

THRESHOLD VALUE FOR FUEL SYSTEM MALFUNCTION CRITERIA
| Amount of air (g (oz)/s) | 0(0) | 3.2 (0.113) | 6.4 (0.226) | 9.6 (0.339) | 12.8 (0.451) | 16 (0.564) | 19.2 (0.677) |
| fsobdL1 (%) | 40 | 40 | 33.2 | 26.5 | 26.5 | 26.5 | 26.5 |
Time Needed for Diagnosis : 10 seconds x 5 times
Malfunction Indicator Light Illumination : 2 continuous driving cycles.
Judge OK when the malfunction criteria below are completed for 10 seconds or more.
