P024B OBD-II: Charge Air Cooler Bypass Control "A" Stuck
P024B Severity
Will P024B 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 P024B?
The Air Flap Actuator restricts airflow through the charge air cooler. The engine control module (PCM) controls the Air Flap Actuator. If the PCM cannot control the actuator, it will set code P024B.The PCM may also disable the turbo or supercharger to prevent further damage to the system. The Charge Air Cooler Bypass Position Sensor is built into the Air Flap Actuator on most vehicles.
