The crankshaft is one of the most important components of an engine that converts the pistons’ reciprocating motion into a rotational movement, making your car move. The crankshaft position sensor monitors the speed and location of rotation.
These materials will help lubricate your motor to run smoothly and more efficiently. Furthermore, they provide real-time data to the Engine Management Unit (EMU) and use it for timing fuel injection and ignition as needed, which greatly helps the engine work even more efficiently on less fuel. One of the major observations regarding this is that having a crankshaft position sensor can help you avoid misfires, starting problems, and stalling.

When you look closely at the crankshaft, you will see a strong magnet placed nearby. Around the crankshaft, steel pins or pegs are set up at even intervals. This magnet always creates a steady magnetic field. Once the engine starts and the crankshaft begins to turn, the steel pins move within this magnetic field. This motion changes the magnetic field, creating an alternating current (AC) signal.
This signal is then sent to the Engine Management Unit (EMU). The EMU uses this data to figure out how fast the crankshaft is turning and its exact position. This helps the EMU control the timing for fuel injection and ignition, ensuring the engine runs efficiently.
An engine’s performance comes from how its internal components run within set speeds. The crankshaft position sensor tracks the motion of the crankshaft. The onboard system, therefore, tunes the engine’s performance with adjustments made in real time upon receiving that information. When you push the accelerator in, the computer can still adjust the engine’s speed based on data from that sensor. It compares the speed of the crankshaft at all times to the optimum and adjusts it accordingly to be smooth and provide the best energy.
The camshaft positional sensor estimates the position of the camshaft and additionally contributes to the specialty of fuel injection time. Similarly, the crankshaft sensor monitors the position and the pace of the crankshaft to make the engines fire in the right manner. These two sensors are very effective and they complement each other depending on the status of the engine.
However, the camshaft sensor proves to be specialized for targeting the camshaft which is entirely different from the sensor that targets the crankshaft. Therefore, they execute different operations as far as the management of the engine is concerned.
Just like a crankshaft sensor, the Camshaft position sensor also presents symptoms when it is not working as it is supposed to. If these symptoms are present, then one could be having a hard time executing some of the basic operations like having a rough running engine, low mpg among others or even having difficulties in igniting the fuel in the vehicle. Therefore, if one is broken, you should track these two sensors on this matter and look for help.
Proper maintenance can prolong the service of your crankshaft position sensor. Here are a couple of tips:
