The camshaft sensor is broken. How does the engine react?

For novice car owners, they often pay attention to the performance of some common car failures. To a large extent, they will help everyone understand the health of the car. Many experienced driving masters can easily pass some abnormal car conditions. Found the problem with the car. Today we received a question from a friend: the camshaft position sensor is broken, what is the reaction of the engine? Now, let’s take a look at the introduction of the editor of Beimai.com.

First, I will introduce the role of the camshaft position sensor.

The camshaft position sensor is also called the cylinder discriminating sensor. The function of the camshaft position sensor is Collect the position signal of the valve camshaft and input it to the ECU so that the ECU can identify the top dead center of the cylinder to perform sequential fuel injection control, ignition timing control and deflagration control. In addition, the camshaft position signal is also used to identify the timing of secondary ignition when the engine is started. The function of the camshaft position sensor is to determine the valve opening to ensure the ignition timing. When the crankshaft position sensor fails, it can be used for short-term emergency ignition.

How will the engine respond if the camshaft position sensor is broken?

It can be seen that the camshaft position sensor has a very large effect on the car, and if the camshaft position sensor is broken , The impact on the engine and the car is also very large. Usually, the camshaft sensor is broken, there will be the following kinds of failures:

1. The ignition is not working

The camshaft position sensor can determine the ignition sequence. If it is broken, it will cause the ignition. The fire is not working, the engine is not easy to start.

2. It is difficult to add fuel

3. The engine is weak

After the camshaft position sensor is broken, the ECU cannot detect When the position of the camshaft changes, the position change of the camshaft cannot be detected correctly, which affects the intake and exhaust volume of the near-exhaust system, thereby affecting the engine performance.

4. Fuel consumption increase

The camshaft position sensor is broken and the computer will spray fuel in an orderly manner! This will cause fuel consumption, vehicle weakness, and speed failure!

5. The car trembles

6. The fault light keeps on

7. Suddenly turns off when the car is hot

The camshaft position sensor The function is very important. If the camshaft position sensor is broken, it will have a certain impact on the operation of the engine. Therefore, when you find that the car has the above abnormal conditions, you must not take it lightly and go to a professional repair shop to check it.

Whether it's automation or artificial intelligence, the rapid convergence of technology and business often determines performance camshaft’s competitiveness.
