Audi a63.2p0 12 1 fault code

Throttle position sensor fault code. Several aspects:

1. The throttle position sensor is damaged. But it's not easy, so we can ignore it for the time being.

2. The surface of the throttle position sensor is dirty. Most cars have this situation and need to clean the throttle.

3. The plug of the throttle position sensor harness is loose. Unplug the plug and plug it in again.
