A technical documentation that provides information about camshaft position sensors in a vehicle. It details the use of four Hall effect sensors, one for each camshaft, and describes the True Power On (TPO) sensor technology capable of detecting cam position with a stationary engine. The document illustrates the staggering of camshaft signals and notes that the signal is low in the absence of a window.
