Code P2618 2018 Chevrolet Silverado Description

The Crankshaft Position Sensor is 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 is running, the high and low parts of the teeth cause the gap with the sensor to change. The changing gap causes the magnetic field near the sensor to change. The change in the magnetic field causes the voltage from the sensor to change.
The Diagnostic Trouble Code (DTC) will be set when the Crankshaft Position Signal Output Circuit is short to ground or open for greater than 5 s.
