Abstract
A method for monitoring a coolant temperature sensor of a motor vehicle is provided, wherein an actual value (TCOist=TCOSt) of a coolant temperature (TCO) is determined by a coolant temperature sensor when an internal combustion engine of the motor vehicle is started (t=tSt), and the coolant temperature sensor is diagnosed as a functional coolant temperature sensor if the actual value (TCOist) of the coolant temperature (TCO) drops briefly (tmin0) when the internal combustion engine is started (t=tSt). A controller, e.g., an engine controller, for performing such method is also provided.
