P0049 OBD-II: Turbocharger/Supercharger Turbine Overspeed
P0049 Severity
Will P0049 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 P0049?
The Turbo/Supercharger has a sensor that tells the engine control module (PCM) how fast it is spinning. If the Turbo/Supercharger spins too fast, the PCM will set code P0049.This may send the vehicle into "limp home mode", limiting the amount of power out of the engine, to protect other components from being damaged.
