Throttle position problem - Toyota Yaris Forums

If you are leery of the dealer, try resetting the ECU first. This exact issue happened with our 08, and an ecu reset fixed it. The ecu "learns/adapts" to your driving, and sometimes it learns something incorrect. I worked with our master tech, and we decided it had to be the TB; I had my TB replaced under power train, but the replacement didn't fix it. I later reset the ECU doing something else, and voila, it was all better.

Agreed. Somtimes, resetting the ECU (or any "computer") can solve problems........ not often but, worth a try.
