6.11 Throttle Body Alignment (TBA/TPS)
It’s very common to see a customer pull into the shop with a Volkswagen or Audi that just will
not idle correctly. One of the possible causes is that the throttle position is not known. When the
motion range is not known, the ECU simply has no idea where to set the throttle. The ECU
must know the full range of motion of the throttle in order for it to properly control the engine.
Using the throttle position sensors in the throttle body, the ECU learns the full open and full
closed positions through various states (idle, part throttle, WOT) known as a Throttle Body
Alignment (TBA).
When one of the following conditions came up, a TBA is needed.
1. The vehicle's battery has been disconnected and re-connected.
2. The ECU has been removed and reinstalled.
3. The Throttle Body has been cleaned or removed and reinstalled.
4. The Accelerator Pedal has been removed and reinstalled.
