The present invention relates to an apparatus and a method for starting an engine of a mild hybrid electric vehicle. The apparatus for starting an engine of a mild hybrid electric vehicle according to an embodiment of the present invention can include: an ignition switch including a plurality of contact points; a mild starter/amp (generator) that includes a stator and a rotor disposed inside the stator to generate power by starting an engine or through an output of the engine; an MHSG wheel integrally rotated with the rotor and having at least three teeth on the circumference; an MHSG location sensor that detects the locations of the teeth; and a controller that determines a top dead point of a cylinder set based on a signal of the MHSG location sensor and starts the engine by driving the MHSG. The present invention provides an apparatus and a method for starting an engine of a vehicle by which the engine can be started by using an MHSG wheel having teeth on the circumference.
