1. A method for automatically detecting clogging of a sensor pipe extending between a pressure sensor and an exhaust manifold of an internal combustion engine, wherein the pressure sensor enables to record a signal representative of a relative pressure over time, the method comprising:
monitoring, from a time the internal combustion engine has been turned off, the signal over a second period of time (T2), the sensor pipe being considered clogged when an integral of the signal over the second period of time (T2) is greater than a second threshold; and
triggering an alert towards an operator of the internal combustion engine when the sensor pipe is considered clogged.
