FIELD: internal combustion engines.
SUBSTANCE: invention can be used in supercharged internal combustion engines. Method for supercharged engine consists in determining engine operating conditions. A command which sets the position of the compressor recirculation valve (RCC) is set. Differences are determined between deterioration of compressor recirculation valve throttle and compressor recirculation valve position sensor based on throttle inlet pressure or compressor recirculation valve throttle set by command. Disclosed is version of method for supercharged engine.
EFFECT: technical result consists in detection of difference in RCC throttle state deterioration from RKK position sensor deterioration.
