DTC Detection Logic
NOTE:
If DTC P050A or P050E is displayed with other DTC, first perform the trouble diagnosis for other DTC.
| DTC No. | Trouble diagnosis name | DTC detecting condition | Possible cause |
|---|---|---|---|
| P050A | Cold start idle air control system performance | ECM does not control engine idle speed properly-when engine is started with pre-warming up condition. |
|
| P050E | Cold start engine exhaust temperature too low | The temperature of the catalyst inlet does not rise to the proper temperature when the engine is started with pre-warming up condition. |
