P226B OBD-II: Turbocharger/Supercharger Boost Pressure Too High - Mechanical
P226B Severity
Will P226B 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 P226B?
The engine control module (PCM) uses sensors to determine if the Turbocharger/Supercharger is providing the requested amount of boost. If the PCM determines that the requested amount of boost is not being provided, the PCM will set code P226B.
