Abstract
A temperature sensor arrangement including a temperature sensor having a measuring element formed as a temperature-dependent variable resistor, and an electronic circuit for function checking of the temperature sensor. The electronic circuit includes a temperature-independent test resistor arranged parallel to the measuring element, first and second semiconductor switches arranged in current circuits of the measuring element and the test resistor, respectively, and a control conductor and a voltage converting element for alternatively connecting the two semiconductor switches to an auxiliary input of the temperature sensor.
