P012B OBD-II: Turbocharger/Supercharger Inlet Pressure Sensor Circuit

P012B Severity

Moderate

Will P012B 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 P012B?

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 P012B.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.
