The research was conducted for the purpose of determining the possibility of diagnosing faulty MAP sensor readings of an automobile spark ignition engine. In that sense, an engine with no air-flow meter, operating under steady-state conditions, was tested on the test stand. The engine fuel system was operating in a closed-loop mode with the oxygen sensor. The tests were carried out in several operating points, first with the engine operating without any faults and then with a reading fault of a MAP sensor. Three different intensities of a mentioned fault and their impact on the engine speed sensor and MAP sensor signals were considered in the study. The measured values were compared with the corresponding values obtained with the engine operating under no-fault conditions. The results are shown in the diagrams followed by the appropriate comments.
