P050A OBD-II: Cold Start Idle Air Control System Performance
P050A Severity
Will P050A go away on its own?
Once the vehicle's onboard system no longer detects the issue, most codes will disappear on their own. If your vehicle still has this code, however, it should be properly diagnosed to avoid a more serious problem.
For a proper diagnosis, RepairPal Certified shops have the equipment, tools, and expertise.
Moderate severity codes might not threaten the vehicle's safety or functionality immediately, but you should still get it diagnosed within a reasonable time frame to keep your car running well.
What causes OBD-II fault code P050A?
The engine's control module (PCM) does everything possible to help the catalytic converter warm up as quickly as possible in an effort to reduce emissions. Part of the control module's logic in the this process is to increase the amount of air flowing through the engine on startup and adjust the engine's timing accordingly. If the airflow through the engine does not match the PCM's request for airflow, the PCM will store code P050A.
