Diagnostic Method
If the duration of time while the following conditions are met is longer than the time indicated, judge as NG.
JUDGMENT VALUE
| Malfunction Criteria | Threshold Value |
|---|---|
| |Intake air temperature (air flow sensor) 21 sec. after engine start - Engine coolant temperature at engine start| | More than value of Map1 |
| |Intake air temperature (air flow sensor) 21 sec. after engine start - Ambient air temperature 21 sec. after engine start| | More than value of Map2 |
MAP 1
| Ambient temperature (°C (°F)) | -30 (-22) | 30 (86) | 45 (113) | 60 (140) |
|---|---|---|---|---|
| |Intake air temperature (air flow sensor) 21 sec. after the first engine start - Engine coolant temperature at the first engine start| (°C (°F)) | 12 (21.6) | 12 (21.6) | 22 (39.6) | 22 (39.6) |
MAP 2
| Ambient temperature (°C (°F)) | -30 (-22) | 30 (86) | 45 (113) | 60 (140) |
|---|---|---|---|---|
| |Intake air temperature (air flow sensor) 21 sec. after the first engine start - Ambient air temperature 21 sec. after the first engine start| (°C (°F)) | 20 (36) | 20 (36) | 32 (57.6) | 32 (57.6) |
Time needed for diagnosis: Less than 1 s
Malfunction indicator light illumination: Illuminates when malfunction occurs in 2 continuous driving cycles.
