  "textContent": "Various embodiments may include a method for operating an internal combustion engine having a wastegate turbocharger comprising: measuring an intake pipe pressure; determining a cylinder air mass from the pressure; injecting an amount of fuel into a cylinder of the internal combustion engine based on the air mass; determining and a plausible intake pipe pressure gradient for a current engine operating point; calculating a gradient of the measured intake pipe pressure during a full-load acceleration; comparing the stored plausible intake pipe pressure gradient to the calculated gradient; identifying manipulation of the intake pipe pressure sensor if the difference between the stored plausible intake pipe pressure gradient and the calculated gradient exceeds a selected threshold value; and limiting a power output of the engine if manipulation is identified.",
