The only way it could have been moved during the brake job is if someone intentionally went in there is see how dirty it was in an effort to sell a throttle cleaning service.
Electric throttle control actuator consists of throttle control motor, throttle position sensor. The throttle control motor is operated by the ECM and it opens and closes the throttle valve. The current opening angle of the throttle valve is detected by the throttle position sensor and it provides feedback to the ECM to control the throttle control motor to make the throttle valve opening angle properly in response to driving condition.
A piece of carbon may be holding it open in which case it may be as simple as cleaning the throttle bore. However in cases such as a nissan, it will typically ruin the throttle body actuator. Not sure on yours, I wouldn't attempt to move it for fear of this.
IF the throttle wasn't cleaned then it may help. If not, it will need to be tested. A scanner is how the codes should be cleared and see if it returns.
Do call the brake shop and ask if they would have looked at it. It may state it on the bill if they recommended cleaning it, in which case it was likley moved at that point.
