What is a cold start Idle Air control System?
The term cold start refers to an engine drivability strategy that is implemented only when the engine is at (or below) ambient temperature. Controlled by the PCM, the IAC valve is responsible for regulating air flow through the throttle body and into the engine intake manifold when the engine is at idle.
What does the error code p050a stand for?
Error Code P050A is defined as Cold Start Idle Air Control System Performance. This is a generic trouble code, meaning it applies to all vehicles equipped with OBD-II system, particularly those made in 1996 up to present.
What is the p050a cold start idle air control system?
Since desired RPM level is precisely and aggressively targeted by the PCM, the valve is moved in very small increments, continuously. If the PCM cannot effectively control the engine RPM level at cold start, a code P050A will be stored and a malfunction indicator lamp (MIL) may be illuminated.
What are the symptoms of OBD code p050a?
Possible symptoms of code P050A vary between slight and barely detectable, to severe driveability issues that can effectively render a vehicle un-driveable. Other possible symptoms may include the following- Rough idle that may vary in severity between applications, depending on the exact nature of the cause
What happens if the p050e is too low?
IF the PCM detects that exhaust temperature is lower than ambient temperature, a code P050E will be stored and a malfunction indicator lamp (MIL) may be illuminated. In most cases, multiple failures will be required for MIL illumination.

How much does it cost to repair a p050a?
Check for damaged components and look for broken, bent, pushed out, or corroded connector’s pins. The cost of diagnosing the P050A code is 1.0 hour of labor. The auto repair labor rates vary by location, your vehicle’s make and model, and even your engine type. Most auto repairs shops charge between $75 and $150 per hour.
What does p050a mean on a Kia Soul?
The check engine light will illuminate when the current requirements are too high or. P050A is a code for higher than expected idle RPM. It happens to all Souls on startup in cold weather at times. Throttle body cleaning, carbon cleaning etc.. can kind of help it but in reality there is no fix for it.
