Abstract
In a method for testing a pressure sensor of a fuel accumulator device in an internal combustion engine, the pressure in the fuel accumulator device is altered using a first actuating variable. The influence of that alteration on the torque generated by the internal combustion engine is determined by a closed loop control system adjusting a second actuating variable to counteract the effect of the first on the torque output by the internal combustion engine. A deviation of the measured alteration from the expected alteration is then calculated.
