Torino, who have not scored in the last 10 meetings with Juventus and have failed to beat their rivals since 1995, were furious at having a late penalty appeal turned down while the hosts notched their 13th straight home win in the league this season.
Juve's win kept them nine points clear of AS Roma, who won 1-0 at Bologna on Saturday, and on course for a third successive title.
Juve have 66 points with Roma on 57 and Napoli a further seven back in third.
Tevez scored the only goal on the half hour when the Argentine brilliantly controlled Kwadwo Asamoah's pass and fired a low shot into the net on the turn.
Torino were by no means outplayed and believed they should have had a penalty when Omar El Kaddouri appeared to be tripped by Andrea Pirlo 10 minutes from time.
