What is the function of a crankshaft position sensor?
One of the most important parts of your vehicle is the engine and its parts like the crankshaft position sensor that keep your engine working properly. The crankshaft position sensor has the important job of monitoring the engine’s many moving parts including the crankshaft, engines valves, and pistons.
Where is the crankshaft position sensor located on a car?
The location of the crankshaft position sensor can vary from one vehicle to another. Obviously it must be close to the crankshaft, so it is most often located on the front underside of the engine. It can usually be found mounted to the timing cover. Sometimes it may be mounted at the rear or the side of the engine.
How does a Hall effect sensor work on a crankshaft?
A Hall effect sensor produces electricity in when it is exposed to a magnetic field. In a crankshaft position sensor, a toothed wheel, spinning with the crankshaft, disrupts the magnetic field.
What should the rpm reading be on a crankshaft sensor?
If the scanner gives a reading between 100 and 500 RPM, then it is working fine. Anything besides that reading indicates a problem with the crankshaft sensor whereas, zero reading suggests that the sensor has failed completely. If you don’t have access to a diagnostic scan tool, you can also test the sensor using a multimeter.
Why does my crankshaft sensor need to be replaced?
The crankshaft sensor can wear or fail due to continuous use over time. In such cases, the crankshaft sensor needs to be repaired or replaced.
