It will depend on the make and model of torpedo. Some have rather sophisticated sonar systems. Others are 'dumb' and simply go in the direction they are pointed.
A torpedo guidance system is a mechanism used in torpedoes to navigate and steer towards a target. It typically consists of sensors, such as sonar or acoustic arrays, that detect the target and measure the torpedo's position and orientation. The data from these sensors is processed by a guidance algorithm, which provides commands to control the torpedo's propulsion and steering, allowing it to intercept the target accurately.

Earlier , in 1776, the the Submarine Turtle used a Spar Torpedo in the revolutionary war. Today. A torpedo is most likely to be a self guiding, electrically driven weapon that could be compared to an underwater missile.
