Functional description
WARNING: This page does not describe the selected car, but rather 45 other vehicles, including the 2016 BMW M5, 2016 BMW 550i xDrive, 2016 BMW 550i, 2016 BMW 535i xDrive, and 2016 BMW 535i. However, it is still accessible from the selected car via links, so may be relevant.
The engine oil pressure/temperature sensor measures the absolute pressure of the engine oil and its temperature. The measured values are output as a pulse-width-modulated signal.
The measuring procedure is based on a micromechanical piezoresistive pressure sensor (silicon) which supplies an output signal proportional to the pressure. Temperature measurement is performed by way of a diode.
The sensor measuring range is 0.5 bar to 10.5 bar at permissible temperatures between -40 °C and 160 °C. The sensor is operated with a voltage of 5 V.
