Here’s what you need to know about the crank shaft position sensor…

What is a Crank Shaft Position Sensor and How Does it Work?

A Crankshaft Position Sensor (CPS) is a device used to monitor the position and rotational speed of the crankshaft in an internal combustion engine. It is typically located near the crankshaft, either at the front or rear of the engine.

The CPS works by sending an electrical signal to a computer when it detects changes in the rotational speed or position of the crankshaft. This signal is then used by the computer to adjust fuel delivery, ignition timing, and other parameters for optimal performance.

The CPS consists of two main components: a magnetic pickup coil and a Hall effect sensor. The magnetic pickup coil generates an alternating current (AC) signal as it passes over magnets embedded in the crankshaft pulley or flywheel. This AC signal is then sent to a Hall effect sensor which converts it into a digital pulse that can be read by an onboard computer system.

The frequency of this pulse indicates how fast or slow the crankshaft is rotating, while its amplitude indicates its position relative to the top dead center (TDC). By monitoring these signals, modern engines can adjust their performance accordingly for maximum efficiency and power output.

Common Symptoms of a Faulty Crank Shaft Position Sensor

A faulty crankshaft position sensor can cause a variety of symptoms in a vehicle. These symptoms may include difficulty starting the engine, stalling or misfiring during acceleration, reduced fuel efficiency, and illumination of the check engine light. In some cases, the vehicle may not start at all.

Additionally, among the other symptoms of a bad crankshaft position sensor; drivers may experience jerking or lurching when shifting gears as well as rough idling and decreased power while driving. If any of these symptoms are present in a vehicle it is important to have it inspected by a qualified mechanic to determine if the crankshaft position sensor is malfunctioning.

The Advantages and Disadvantages of Using an Aftermarket vs OEM Part for the Replacement

When it comes to replacing a part in a vehicle, there are two main options: aftermarket parts and original equipment manufacturer (OEM) parts. Aftermarket parts are produced by third-party companies and are not made by the original manufacturer of the vehicle.

OEM parts, on the other hand, are made by the same company that manufactured the car or truck. Both types of parts have their advantages and disadvantages when it comes to replacing a part in your vehicle.

  • One advantage of using an aftermarket part is that it tends to be less expensive than OEM parts. This can be beneficial for those who need to replace a part but don’t have much money to spend on it. Additionally, aftermarket parts often come with warranties which can provide peace of mind if something goes wrong with them down the line.
  • On the other hand, one disadvantage of using an aftermarket part is that it may not fit as well as an OEM part due to differences in design or manufacturing processes between different companies. Additionally, some aftermarket parts may not last as long as OEM ones due to lower quality materials being used in their construction or because they were not designed specifically for your make and model of vehicle like an OEM part would be.
  • In contrast, one advantage of using an OEM part is that you know it was designed specifically for your make and model so you can rest assured that it will fit properly and last longer than an aftermarket one might due to its higher-quality materials being used during its construction process. Additionally, many times these types of replacement components come with extended warranties from their manufacturers which can provide extra protection if something goes wrong down the line with them too.
  • However, one disadvantage associated with using an OEM replacement component is that they tend to cost more than their aftermarket counterparts do mainly because they were designed specifically for your make and model rather than being mass-produced like most third-party components are today. This means you may end up spending more money upfront when purchasing this type of replacement component compared to what you would pay for its cheaper counterpart from another company instead.
