Abstract
Methods and systems are provided for diagnosing an actuator of a variable inlet compressor coupled in an electric turbocharger. During torque transitions, an electrical power consumption of an electric boost assist motor is observed and used to infer an actual compressor speed and pressure ratio across the compressor. By comparing the measured pressure ratio to a compressor map, it may be determined if the actuator is stuck open or stuck closed.
