P012D Severity
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.
The Turbo/Supercharger inlet pressure sensor tells the engine control module (PCM) how much air is being forced into the engine When the PCM detects an incorrect signal from this sensor, it will set code P012D.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.
