Will the check engine light come on if throttle body is bad?

The throttle body is a component of an internal combustion engine that controls the amount of air that enters the engine. If the throttle body is bad, it can cause the engine to run rich or lean, which can trigger the check engine light to come on. Additionally, a bad throttle body can cause the engine to stall or hesitate, which can also cause the check engine light to come on.
