The Citizens have lost just once in the 2011-12 campaign, and sit proudly at the top of the table, three points ahead of local rivals Manchester United with 17 games left to play.
As Roberto Mancini's men look to win their first top-flight crown since 1968, Johnson says that the title is City's to lose, and has urged his teammates to keep calm and carry on.
"I would be devastated if we didn't [win the title]," the 24-year-old told Sky Sports News. "Obviously the position we've got ourselves in, it is up to us not to give it away now.
"We're top of the league by three points, it is up to us to not make mistakes, but me and the lads don't really want to think about that."
After successfully guiding City to FA Cup victory last season, Mancini's expensively assembled squad received further investment to continue in their hunt for glory.
Johnson knows that the financial backing from Etihad Stadium owners has given the club an advantage in some respects, but feels the players deserve recognition for their efforts this year.
"Everyone knows we deserve to be where we are now," he added. "To throw it away would be a disaster for me personally."
