Abstract
Disclosed is a shift range switching apparatus of an automatic transmission which can improve the durability over the conventional shift range switching apparatus. An ECU is operative to rotate an actuator in a predetermined direction (Step S) in the state of the automatic transmission switched to a predetermined shift range (Step S), and thereafter the actuator is deenergized (Step S). The reference position of the actuator corresponding to the predetermined shift range is detected (Step S) in accordance with the fluctuation of the count value counted by an encoder when the actuator is deenergized (Step S).
