What Is a Crank Position Sensor

The crankshaft position sensor is an electronic component designed to fine-tune the timing of a vehicles engine. The sensor works with the vehicles on-board computer to ensure the vehicle runs at optimal performance.

Purpose

The crankshaft position sensor monitors the position and speed of the crankshaft to control the ignition system timing. The component aids in variable valve timing by monitoring the movement between the vehicles pistons, valves and the engine, noting the engines revolutions per minute.

Function

Made from magnets and an inductive coil, the crank position sensor is positioned next to the crankshaft. The crankshaft has several pins spaced an equal distance apart which is read and calculated by the magnets within the sensor as the crankshaft spins.

Location

These sensors are located in the lower front of the engine block either directly next to the crankshaft, within the main crank pulley or the flywheel. The crankshaft position sensor can be identified as a long, thin, black cord.
