Speed sensor for 2002 vw golf 2.0 engine - 2002 Volkswagen Golf

Honestly it is not very expensive to replace, but it is not extremely important. What it does is measure the oxygen/fuel level coming out of the engine. This tells the computer that the engine is either using the right air/fuel mixture or allows the computer to change the mixture slightly to allow the car to run properly. You could pull the sensor out and clean the terminal as it usually has alot of carbon build up due to its location, but this is normally a temporary fix. I hope this helps you with your problem.

If not mistaken on a 95 it is cable operated not electronic. So check if it is connected securely behind the speedo head. The cable goes through the firewall into another box behind the wall. From that box which is where reset button is located, the cable should go directly to the differential housing of the transmission.
