What is the purpose of the crankshaft position sensor in an Audi 80?

I recently purchased an Audi 80 and have noticed a sensor located near the engine that I am not familiar with. I am curious about its function and role in the performance of the car.

The crankshaft position sensor in an Audi 80 is responsible for monitoring the rotational speed and position of the crankshaft. It sends this data to the engine control unit, which uses it to determine the ignition timing and fuel injection timing.

This sensor is crucial for the overall performance and efficiency of your Audi 80 engine. A faulty crankshaft position sensor can cause issues such as stalling, misfires, and difficulty starting the car. It is important to have it checked and replaced if needed.
