| DTC P050A |
Cold start idle air control system performance |
| DETECTION CONDITION |
- Actual Idle speed is lower than expected by 100 RPM
for 8.4 s
when target idle speed is above 0 RPM
at cold start or ignition retard value is above 8.9 °C {48 °F}.
NOTE:
- If atmospheric pressure is less than 72.3 kPa {542 mmHg, 21.3 inHg}
or intake air temperature is below -10 °C {14 °F},
the PCM cancels diagnosis of P0506.
Diagnostic support note
