What is the function of the camshaft position sensor in an Audi 80?

I recently bought a used Audi 80 and I noticed that it has a camshaft position sensor. I'm not sure what it is for and if it's important to the functioning of my car. Can someone explain it to me?

The camshaft position sensor in your Audi 80 is responsible for sending signals to the engine control unit regarding the position of the camshaft. This information is used to regulate the fuel and ignition systems, ultimately affecting the performance of your car. It's a crucial component in ensuring your engine runs smoothly.

Think of the camshaft position sensor as your car's internal GPS. It continuously tracks the position of the camshaft and sends that data to the engine control unit, which then adjusts the fuel and ignition systems accordingly. Without it, your engine may exhibit poor performance and even stalling.
