Diagnostic Method
WARNING: This page is about a different variant/trim than selected.
Compare the diagnostic value with the threshold value, and if a condition meeting the criteria continues for 10s x 3time(s) or more, judge that there is a fault in the fuel system.
JUDGMENT VALUE SPECIFICATIONS
| Malfunction Criteria | Threshold Value |
|---|---|
| Offset amount of main feedback compensation | Less than value of Map |
WARM-UP INCREASE COMPENSATION - MAP
| Warm-up increase compensation coefficient | 0 | 0.1 | 0.2 | 0.3 | 0.4 | 0.416 |
|---|---|---|---|---|---|---|
| Threshold Value | 0.65 | 0.56 | 0.48 | 0.42 | 0.36 | 0.35 |
Time needed for diagnosis: 10s x 3time(s)
Malfunction indicator light illumination: Illuminates when malfunction occurs in 2 continuous driving cycles.
NOTE:
When a short period (distance) driving from the engine start to stop is repeated, engine warm-up followed may cause detection of P0172 due to gasoline evaporation within the engine oil and blow-by gas increase.
