the electronic throttle control light came on when the vehicle was started and remained on until I reached my destination (about 25 minutes ). There was no noticeable difference in the way it ran and the light was off when I restarted the car. Does this indicate a problem?

Short answer - yes. But the degree of the problem is unknown. A diagnosis is necessary to determine what happened to cause the light to come on. You could have an intermittent concern that may reoccur causing more serious issues. Worth looking into.
