INTERNAL COMBUSTION ENGINE SYSTEM

The present disclosure relates to an internal combustion engine (ICE) system comprising: an internal combustion engine; a turbocharger arrangement, the turbocharger arrangement having a turbine arranged in an exhaust gas conduit, the exhaust gas conduit extending between the internal combustion engine and the turbine, and further a compressor disposed in an inlet manifold, the inlet manifold extending between the compressor and the internal combustion engine; a controllable backpressure valve being located in the exhaust gas conduit, the controllable backpressure valve being configured to control the pressure within the exhaust gas conduit; a pressure sensor disposed in the exhaust gas conduit, and further in-between the controllable backpressure valve and the turbine, the pressure sensor being configured to measure an exhaust gas pressure downstream the controllable backpressure valve; a speed sensor configured to measure a compressor speed; and a control system for determining an operational status of the pressure sensor.
