Sebastian Vettel's poor performance at the Brazilian Grand Prix has been traced to a sensor problem that was affecting the handling of his Ferrari.
The German, who started the race in second place having qualified 0.096s off eventual winner Lewis Hamilton, finished the race in a distant sixth-place.
Vettel was overtaken by Valtteri Bottas at the start and lost two more positions to Max Verstappen and Kimi Raikkonen on lap four of the race He was able to get ahead of teammate Raikkonen through the pit stops but Ferrari used team orders to swap its drivers around, allowing the Raikkonen to have the chance to attack Bottas and eventually secure third place.
