The Camshaft Position Sensor is an inductive 2-wire sensor with a typical permanent magnet resistance of 125.5±17 Ohm used in an internal combustion engine to monitor the position or rotational speed of the crankshaft while this information is used by engine management systems to control the fuel injection or the ignition system timing and other engine parameters. It is powered by 5V DC and it produces a quadratic wave function that varies according to the engine RPM. A failed crankshaft position sensor will often cause your Volvo S60 to crank without starting or may cause it to die intermittently.
