Abstract: One or more techniques and/or systems are disclosed for identifying a position of an engine, such as the position of the pistons, camshaft, and/or crank shaft, during engine starting. In some implementations, a magnetic reluctance sensor can detect the reluctance from a proximate timing gear, resulting in an input voltage signal indicative of the detected reluctance. The input voltage signal can be converted to a digital voltage signal. A trigger threshold can set to identify a detection window. During the detection window, a zero-cross of the input voltage signal is detected to identify an engine position, and any other zero-crossing signals are not identified, thereby mitigating the effects of noise at the slow starting speeds.
