ABSTRACT:
A mass airflow sensor measurement correction system for a turbocharged diesel engine operating under transient conditions includes a signal input device that generates an engine speed signal based on an engine speed of a turbocharged diesel engine. A control module receives the engine speed signal and calculates a correction value of mass airflow from a differential of the engine speed signal and a constant.
