DTC P050A:00: Notes

DTC P050A:00 (L3 WITH TC) DETECTION CONDITION & POSSIBLE CAUSES

DTC P050A:00	Cold start IAC system performance problem
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 the cold start or ignition retard value is above 6 °. NOTE: If the 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 the diagnosis of the DTC P050A:00. Diagnostic support note This is a continuous monitor (cold start emission reduction strategy monitoring). The 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 first drive cycle. FREEZE FRAME DATA (Mode 2)/Snapshot data is available. The DTC is stored in the PCM memory.
POSSIBLE CAUSE	Air into fuel line by exchange or re-installation Air suction in intake-air system Electronic throttle control system malfunction Throttle valve stuck or blockage PCM malfunction

Cold start IAC system performance problem

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 the cold start or ignition retard value is above 6 °.

NOTE:

If the 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 the diagnosis of the DTC P050A:00.
