Heat the oil in a 4-quart saucepan over medium-high heat.
Add the turkey, onion, chili powder, cumin, oregano, black pepper and garlic powder. Cook until turkey is well browned, stirring frequently to break up meat.
Stir the broth, salsa, sugar, beans and corn into the saucepan.
Heat to a boil. Reduce the heat to low.
Cover and cook for 30 minutes. Stir the chili occasionally while cooking.
