The article focuses on the fault not diagnosed by the OBD system. Apart from mechanical damages sensor faults are a serious group. Although the sensor values are constantly monitored, some errors are not detected. The article presents a diagnostic model of SI engine, which generates the control and work parameters of the engine for the efficient state. The parameters obtained from the reference model can be compared with the parameters measured for the engine in any operating condition. Based on the model the impact of sensor faults for other parameters was analyzed. Some errors can be masked by the adaptive control system of the engine, which changes the parameters of the engine control. Simulation tests were verified on the test bench.
