The ECM uses this data to determine the timing of the ignition, as well as the timing of the fuel injection that the engine requires. If we try to explain it in simpler words, the crankshaft position sensor monitors within the engine, the location of the camshaft.
The camshaft position sensor works in tandem with the crankshaft position sensor to monitor the engine’s timing which, in turn, affects the efficiency of fuel delivery and the sparking mechanisms. This is why the sensor is located either next to camshaft or the crankshaft itself. The Camshaft Position Sensor Is GENERALLY Used In All Modern Sequentially Fuel Injected Engines.
As you will remember from earlier in this blog, the camshaft’s function is to ensure the engine’s valves open and close at the right time to enable ignition and to exhaust burnt charge. As the sensor detects the position of the camshaft, it transmits this information to the engine control unit of the vehicle. By knowing which cylinder is approaching top dead centre, the engine ECU can adjust fuel injection timing or when to energise the ignition coils to enable a smooth combustion process. The information that it gathers thus, it uses the same to optimize the timing of fuel injection in the engine. This data is used to determine the ignition timing and fuel injection timing. On this page, you can find out how a fault on the camshaft sensor can manifest itself, and which steps should be taken during troubleshooting. The main task of this component is to analyze the position or the rotational speed or the rotational speed of the crankshaft.
One of the important components of your vehicle’s engine management system is the crankshaft sensor or crankshaft position sensor. The camshaft sensor enables the engine control to determine the exact position of the crankshaft drive. 6.1K views View 7 Upvoters This rotation is monitored by the camshaft position sensor. The camshaft position sensor, in conjunction with the crankshaft position sensor, serve the function of cylinder identification. This whole setup allows the camshaft to function. The camshaft position sensor is a crucial part of the engine management system that ensures that the engine runs smoothly.
The position sensor on your car’s camshaft continually assesses the frequency at which the camshaft is turning. The sensor is responsible for collecting information about the camshaft speed of the vehicle and sending it to the engine management system (ECM). This information is required to calculate the ignition point and injection point, among other things. This is to fine tune ignition timing and fuel injection timing after the vehicle has started. The camshaft position sensor gathers information about the vehicle’s camshaft speed and sends it to the vehicle’s engine control module (ECM). The camshaft rotates into a certain position to control the intake and exhaust valves. Although this article concentrates on the basics of Crankshaft Position Sensors; you can apply most of this info to the Camshaft Position Sensors too.
The camshaft position sensor is typically referred to as a CMP; the crankshaft position sensor is typically referred to as a CKP.
