Abstract
A system for an engine includes an edge detection module and a correlation calibration module. The edge detection module (i) detects edges of a camshaft of the engine using a camshaft position sensor, and (ii) detects edges of a crankshaft of the engine using a crankshaft position sensor. The correlation calibration module calibrates a correlation between the crankshaft and the camshaft based on the detected edges of the crankshaft and the camshaft, respectively.
