Structure and inner electrical connection
WARNING: This page does not describe the selected car, but rather 7 other vehicles, including the 2017 BMW X3, 2016 BMW X3, 2015 BMW X3, 2014 BMW X3, and 2013 BMW X3. However, it is still accessible from the selected car via links, so may be relevant.
The measuring procedure is based on Hall IC. The output signal uses a flank to show Low status and a gap to show High status. The camshaft position sensor employs the same basic operating concept as the crankshaft position sensor. However, the camshaft sensor wheel differs fundamentally. A special mark pattern enables emergency operation in the event of failure of the crankshaft sensor. However, the resolution of the camshaft sensor signal is too imprecise to replace the crankshaft sensor during normal operation.
