DTC P050A: Notes

DTC P050A [L3] DETECTION CONDITIONS AND POSSIBLE CAUSES

DTC P050A	Cold start idle air control system performance
DETECTION CONDITION	The actual idle speed is lower than expected by specified for 8.4 s when the target idle speed correction value for cold start is above 0 rpm or ignition retard value is above 7 °. 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 P050A:00. Diagnostic support note This is a continuous monitor.(Cold start emission reduction strategy monitoring) MIL illuminates if the PCM detects the above malfunction condition in two consecutive drive cycles or in one drive cycle while the DTC for the same malfunction has been stored in the PCM. PENDING CODE is available if the PCM detects the above malfunction condition during the first drive cycle. FREEZE FRAME DATA (Mode 2/Mode12) is available. DTC is stored in the PCM memory.
POSSIBLE CAUSE	Air suction in intake air system Electronic throttle control system malfunction Throttle valve stuck or blockage PCM malfunction

DTC P050A

Cold start idle air control system performance

DETECTION CONDITION

The actual idle speed is lower than expected by specified for 8.4 s when the target idle speed correction value for cold start is above 0 rpm or ignition retard value is above 7 °.
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 P050A:00.

Diagnostic support note

This is a continuous monitor.(Cold start emission reduction strategy monitoring)
MIL illuminates if the PCM detects the above malfunction condition in two consecutive drive cycles or in one drive cycle while the DTC for the same malfunction has been stored in the PCM.
PENDING CODE is available if the PCM detects the above malfunction condition during the first drive cycle.
FREEZE FRAME DATA (Mode 2/Mode12) is available.
DTC is stored in the PCM memory.
