Do you have idea about how a crankshaft position sensor works? . If not no worries this article will cover in detail what it is, its key functions, and working. Let’s get in to detail.

What is a Crankshaft Position Sensor? 

Crankshaft position sensor is a device that gauges the rotation speed and precise position of the engine crankshaft. Without CKP sensor, car engine won’t work. Mostly it is installed near the central pulley but sometime, it’s also installed in the engine cylinder block or at the transmission bell housing.

Crankshaft position sensor is present in almost every vehicle. It will regulate the rotational speed and position of the crankshaft. The position sensor will send important reports to the control unit to make necessary adjustments in case of failure or malfunctioning.

Working of Crankshaft Position Sensor?

The Crankshaft Position Sensor is a device utilized to affirm the crankshaft’s rotation as the engine is moving while providing feedback in the form of data back to the main computer. The sensor is mainly located near the crankshaft, engine block, or flywheel, depending on the manufacturer’s design.

An electric pulse chart is made as the crankshaft rotates, and that changes the engine’s speed. That wavelength controls the computer output circuits like the camshaft, fuel injector pulse width, and ignition timing adjustments. The sensor also uses the reflector or stator wheel, which has been connected to the crankshaft.

Symptoms such as engine not starting, random misfiring, and intermittent fasting can be an excellent indication that a sensor is beginning to fail. Often, the sensor will begin to work again after it’s been allowed to cool down.
