The crankshaft position sensor is one of the most important sensors in your car. It is a sensor used in an internal combustion engine to monitor the position or rotational speed of the crankshaft. This information is used by engine management systems to control ignition timing and other engine parameters. Without this sensor, your car will refuse to start. It serves an important function in the normal running of the car.
It is located in your engine in different places. it is important to know the location of the sensor so that it can be replaced if necessary. In this awesome guide, you will quickly find out the crankshaft position sensor location.
Crankshaft Position Sensor: How It Works, & Functions
Crankshaft Position Sensor Location
The crankshaft position sensor measures the position of the crankshaft in the engine of the car.
It detects the crankshaft position and sends the signal to the ECU. The ECU then calculates the injection timing, ignition timing, and engine RPM according to the crankshaft position sensor’s signals.
It is used in many different applications, but the fundamental application of this sensor is to get the speed of rotation of the crankshaft in a car with an internal combustion engine either powered by diesel or petrol.
The crankshaft position sensor location varies from car to car. Its location is different based on make and model, but the common location of the crankshaft position sensor (CKP) sensor is in the lower section of the engine block.
Generally, it sits close to the crankshaft located either in the front, back, middle, or side of the engine. As given off by the name, the crankshaft position sensor is located close to the crankshaft of the car situated in the engine block, so that it can work efficiently consuming the least space possible.
In most Japanese cars with four and six cylinders engines, the crankshaft position sensor is located near the crankshaft pulley. This sensor is attached to the engine block of the car facing toward the rotor of the crankshaft.
It senses the speed of this electrical rotor using teeth and sends the signal to the Electronic Control Unit (ECU) of the car, which uses these readings sent forward by the crankshaft sensor for the calculation through which the ECU of the car determines the rotational speed of the engine.
