DTC codes / P01xx · Fuel and air metering / P012E
P012E indicates that the powertrain control module has detected an intermittent or erratic signal from the turbocharger or supercharger inlet pressure sensor A circuit. The computer expects a stable voltage or pressure reading that changes smoothly with engine operation, but instead sees the signal dropping out, spiking, or jumping unpredictably, which prevents reliable boost control and can trigger reduced power modes.
Guidance is general and written for all OBD-II vehicles. Exact tests and values vary by model, so confirm the fault before replacing parts.
