P012A OBD-II: Turbocharger/Supercharger Inlet Pressure Sensor Circuit
P012A Severity
Will P012A 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 P012A?
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 P012A.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.
OBD II Fault Code
- OBD II P012A
OBD-II Code Powertrain Control Module (PCM) failure is defined as a Turbocharger/Supercharger Inlet Pressure Sensor Circuit
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 P012A.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.
Powertrain Control Module (PCM) failure Symptoms
- Engine may enter limp home mode (reduced performance)
- Lack of boost from the turbo/supercharger
Common Problems That Trigger the P012A Code
