P2618 Meaning
The crankshaft position sensor, also known as the crank position sensor, is an electronic device used in an engine to record the rate at which the crankshaft is spinning. This information is used by the Engine Control Module (ECM) to control ignition and fuel injection. The sensor system consists of a rotating part, typically a disc, as well as a static part, the actual sensor.
When the engine rotates, the high and low parts of the teeth cause a change in the gap with the sensor. The changing gap causes the magnetic field near the sensor to change. The changing magnetic field causes the sensor’s voltage to change.
