  "textContent": "Provided is a fault diagnosis device for temperature sensors. At the time (t2) of a start of an internal combustion engine (1), a thermal equilibrium condition may be established and thus the deviation of temperatures detected by at least two reference temperature sensors from each other may be equal to or less than a predetermined value, with the temperatures detected by the reference temperature sensors being greatly deviated from one detected by a temperature sensor to be subjected to fault diagnosis. In this case, if the temperatures detected by the reference temperature sensors do not drop by a predetermined temperature or more between from the start of the internal combustion engine (1) until a predetermined time elapses, the fault diagnosis device determines that the temperature sensor being subjected to fault diagnosis is faulty. Thus, if each portion of the internal combustion engine (1) has reached a thermal equilibrium state, the fault diagnosis of a temperature sensor to be subjected to fault diagnosis can be carried out even when a predetermined time has not yet elapsed after the internal combustion engine (1) has stopped. It is thus possible to perform fault diagnosis on the temperature sensor with efficiency.",
