Published on December 28th, Innova diagnostic scanners assist you in understanding your vehicle, finding problems, and providing guidance for repairs. You can access the same advanced technology used by professionals, without the high costs or subscription fees. To discuss the common symptoms of the Crankshaft Position Sensor. The electronic control unit ECU uses this information to control fuel injection, the ignition system timing, and other engine parameters.

It is located in the engine of the car. It registers the rate of spinning of the crankshaft. This sensor then passes the information to the ECU and decides optimal fuel injection and regulation of ignition. It is the location of the crankshaft that determines the effectiveness of the gathered data. This is why the sensor is located either next to the camshaft or the crankshaft itself. If we try to explain it in simpler words, the crankshaft position sensor monitors within the engine the location of the camshaft. The information that it gathers thus, it uses the same to optimize the timing of fuel injection in the engine. In case this sensor malfunctions, the computer will be unable to make fine adjustments to fuel injection and the performance of the engine will dip. Here are a few ways in which this sensor functions. If you look at the crankshaft, you will find a powerful magnet next to it. You will also find that there are steel pins or pegs arranged at regular intervals around the crankshaft. This magnet constantly radiates a magnetic field that is steady. As the engine starts and the crankshaft spins the steel pins around the shaft rotate around this field. This causes fluctuation in the field, thus producing an AC alternating current signal.

A crank sensor CKP [1] [2] [3] is an electronic device used in an internal combustion engine , both petrol and diesel, to monitor the position or rotational speed of the crankshaft. This information is used by engine management systems to control the fuel injection or the ignition system timing and other engine parameters. Before electronic crank sensors were available, the distributor would have to be manually adjusted to a timing mark on petrol engines. The crank sensor can be used in combination with a similar camshaft position sensor CMP [4] [5] [3] to monitor the relationship between the pistons and valves in the engine, which is particularly important in engines with variable valve timing. This method is also used to "synchronise" a four stroke engine upon starting, allowing the management system to know when to inject the fuel. It is also commonly used as the primary source for the measurement of engine speed in revolutions per minute.

OK, so far you've also learned that the two wire type also known as a magnetic pulse generator type sensor, among several names produces an analog signal. By now you may be wondering what type of signal the three wire type Hall Effect type sensor produces? The answer is: a digital signal. Now you might be asking yourself, "what the heck is a digital signal? Let's find out. A digital signal is a DC voltage signal remember that the analog signal is an AC voltage signal.

These are the most common bad crankshaft position sensor symptoms:. The failing CPK can not provide the right information about the position of a piston in the engine, causing a misfire. Prolonged impulse marks the synchronization pulse and each of the other shows the tooth passing by the sensor. In the example, the impeller interposes between the magnet and the sensitive element. This flow variation induces a variable voltage in the pickup coil — in the form of pulses, synchronized with the teeth passing by the magnet.

Another type of crank sensor is used on bicycles to monitor the position of the crankset , usually for the cadence readout of a cyclocomputer.

The most compromised are: Engine speed sensors: The engine may not run or stop abruptly. This sensor then passes the information to the ECU and decides optimal fuel injection and regulation of ignition. More information at: www. In a diesel, the sensor will control the fuel injection.

Modern vehicles are jam-packed with sensors that keep everything operating the way it should.

In the example, the impeller interposes between the magnet and the sensitive element. Hit space bar to expand submenu Products. Whenever teeth or marks pass by the magnetic sensor, the reluctance of the magnetic circuit decreases; otherwise, the reluctance increases. Engine speed indicator takes speed indication also from this sensor. Get Started. It registers the rate of spinning of the crankshaft. When performing repairs you should be careful not to allow deformation of the cogwheel because this can lead to an engine collapse. If you look at the crankshaft, you will find a powerful magnet next to it. While both sensors provide critical data to the ECM for engine control, they monitor different components. Currently, these are the most used types: Variable reluctance sensor Hall effect sensor Magneto-resistive element MRE sensor Variable Reluctance Sensor This sensor consists of a permanent magnet with a pickup coil over it.
