What happens if the camshaft sensor is broken?

Camshaft sensor is one of the important components of the engine. If the camshaft sensor fails, the engine may also be damaged, so that it cannot work normally. Therefore, the damage of the camshaft is one of the common faults of the engine. In order to improve everyone's operating efficiency, teaches you how to quickly determine the cause of the wheel camshaft sensor failure.

　　Camshaft sensor fault diagnosis and elimination

　　Automobile engine controlled by electronic system is one of the products of high-tech progress. The electronic system can be used for various purposes through various types of sensors, actuators or electronic control components, so that the engine can be automatically controlled by the electronic system. The camshaft sensor is one of the most important sensors of these important electronic system control components. It is mainly used to check the starting and stopping points on the piston inside the engine and provide the electronic control system with an accurate signal of the position of the piston. This signal will be used to determine when the order of ignition and fuel injection. If the engine cannot receive an accurate signal, the engine will become difficult to start, and it will be very weak when accelerating, and emissions will exceed the standard. And the unstable idle speed, at this time we can boldly judge that there is a problem with the camshaft sensor.

　　 In order to confirm whether the camshaft sensor has failed, we need to check the camshaft sensor. Generally speaking, there are different manufacturers of camshaft sensors, and their manufacturing process and quality are also uneven. There are three main types of camshaft sensors currently on the market-Hall-type camshaft position sensors, photoelectric camshaft position sensors, and electromagnetic camshaft position sensors.

　　 If you want to detect the Hall-type camshaft position sensor, you need to detect based on the principle of the Hall effect. When a current passes through the Hall element, if the direction of the current and the direction of the magnetic field of the Hall element are perpendicular to each other, a trace voltage will be generated on both sides of them, which is called the Hall voltage by the physicist. In order to determine whether the Hall sensor has sent a signal, it is only necessary to use a DC voltage to detect whether the average voltage of the Hall sensor is fixed. If you want to survey the photoelectric camshaft position sensor, you can disconnect the ignition switch, and then use the sensor wire to connect to the plug, then use a multimeter to connect to terminal 3, and then use a voltmeter to detect. If there is no damage, the voltage should be above 4.5V, but if the voltage is 0, it proves that the sensor has failed.

　　What will happen if the camshaft sensor is broken

　　 1. It's hard to add oil

　　 2. The fire is not working

　　 3. Idle speed

　　 4. The fault light keeps on

　　 5. Suddenly turn off the engine while warming up

Crankshaft Position Sensor (Crankshaft Position Sensor, CPS), also known as engine speed and crankshaft angle sensor, its function is to collect the crankshaft rotation angle and engine speed signal, and enter the electronic control unit (ECu), in order to determine the ignition time and fuel injection time. Camshaft position sensor (Camshaft PosiTIon Sensor, CPS) is also called cylinder identification sensor (Cylinder IdentificaTIon Sensor, CIS). In order to distinguish it from crankshaft position sensor (CPS), camshaft position sensor is generally expressed by CIS. The function of the camshaft position sensor is to collect the position signal of the valve camshaft and input it to the ECU, so that the ECU recognizes the compression top dead center of the cylinder 1 to perform sequential fuel injection control, ignition timing control and knock control. In addition, the camshaft position signal is also used to identify the first ignition moment when the engine is started. Because the camshaft position sensor can identify which cylinder piston is about to reach top dead center, it is called a cylinder identification sensor.
