The 33-year-old, who is yet to receive a contract for next season, spent six years with the BAR team, which later became Honda, between 2003 and 2008.
He said that he is looking forward to getting back into a car powered by the Japanese manufacturer.
"I want to be here in 2015," he told reporters. "That is an important year, I think. I've worked for many years with that Japanese engine manufacturer, it will be exciting to work with them again in the future."
Addressing the question of links to Ferrari, he replied: "I am loyal. In the past sometimes I haven't been.
"I think if you are with a smaller team that you can't see a future with, it's the right thing to always look for something better. But when you are with a team like this with the future that this team has, this is a very exciting opportunity for any driver."
The Formula 1 season heads to Monza for the Italian Grand Prix this weekend.
