Abstract
A computer-implemented method is disclosed for diagnostics of NOx sensor(s) of a vehicle. The method comprises—while the electric motor(s) are not driven by the ICE—controlling (by processing circuitry of a computer system) the ICE to operate according to a predefined operational mode, wherein the predefined operational mode has a correspondingly predefined expected, non-zero, NOx sensor response, controlling (by the processing circuitry) the NOx sensor(s) to perform measurements associated with the predefined operational mode of the ICE, and acquiring (by the processing circuitry) corresponding measurement results from the NOx sensor(s) for comparison to the predefined expected NOx sensor response.
