How does the engine coolant temperature sensor work in an Audi 80?

I was wondering about the functionality of the engine coolant temperature sensor in my Audi 80. Where is it located and how does it affect the performance of my vehicle?

The engine coolant temperature sensor is located near the radiator and measures the temperature of the coolant. It relays this information to the engine control module, which uses it to adjust the air/fuel mixture for optimal performance.

If your engine coolant temperature sensor is malfunctioning, you may experience issues such as poor fuel efficiency and engine misfires. It's best to have it checked and replaced if necessary by a qualified mechanic.

To ensure the accuracy of your sensor readings, it's important to regularly flush and replace your engine coolant according to the manufacturer's recommendations. This will prevent any buildup or incorrect temperature readings.
