Code P0501 Volkswagen Description

The P0501 diagnostic trouble code for Volkswagen vehicles indicates an issue with the Vehicle Speed Sensor 'A', specifically related to its range or performance. The Vehicle Speed Sensor (VSS) is a crucial component that measures the speed of the vehicle and sends this information to the engine control module (ECM). This data is essential for various systems in the vehicle, including the transmission, ABS, and traction control. When the VSS is not functioning correctly, it can lead to inaccurate speed readings, affecting the vehicle's performance and overall drivability.

  • I have all the same symptoms. Once I take out the bad sensor and replace it does it have to be coded or programmed.

    Reply to Comment

  • No, you may just have to clear the code. No need to reprogram the new sensor.

  • So I replaced my G 22 sensor and it didn’t correct the issue. I started checking wiring and I don’t have 12 V going to the sensor, it appears to be shorted to ground. Where does that 12 V come from?

    Reply to Comment

  • Let me check if I have the location, what model and year is your vehicle? what sensor did you replaced?

    Reply to Comment

  • I ended up finding out that the 12 V supply for the G22 sensor is grounded out somewhere. It also shares the 12 V supply with the multi-function indicator switch, I can’t seem to find where it’s grounding out though.
