Structure and inner electrical connection
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 oil condition sensor is connected via a bit-serial data interface to the engine control system.
The electronic monitoring circuitry is completely contained within the electronic component and employs capacitance measurement to operate.
The voltage supply is dependent on the engine version (e.g. via terminal 87, terminal 15 or terminal 15N).
The following graphic shows by way of example the voltage supply via terminal 87.
