Code P1554 BMW Description
The detection of each camshaft position is done by an active hall sensor and a cam wheel, "3 asymmetric teeth". The camshaft sensor delivers 3 high and 3 low phases of different lengths per 720°CRK. The high or low pegel of the signal at the reference gap of the crankshaft signal determines the position of the engine within the combustion cycle. With that information, an engine position is calculated from the crankshaft position sensor within a range from [0 to 720]° CRK
