Abstract (en)

[origin: WO2015169551A1] A method is proposed for monitoring the state of opening of a control valve (11) of a coolant circuit (1) of an internal combustion engine (2), wherein the control valve (11) has a valve element (12), which can be actuated by an actuator (22), for enabling and/or blocking a coolant flow in the coolant circuit (1) which has a heat exchanger (3), and has a device for detecting the position of the valve element (12), and the device detects a first actual value, which represents the position of the valve element (12), before the starting of the internal combustion engine (2), and compares the actual value with a reference value which corresponds to a blocking position of the valve element (12).
