A steering angle detecting apparatus includes a steering angle sensor and a diagnostic unit. The steering angle sensor includes two relative steering angle detectors and an absolute steering angle processor. The two relative steering angle detectors detect a plurality of two relative steering angles. The absolute steering angle processor calculates absolute steering angles. The diagnostic unit determines whether an angular signal indicating an absolute steering angle of the absolute steering angles is outputted from the absolute steering angle processor. The diagnostic unit stores a latest absolute steering angle, determines which of the two relative steering angle detectors outputs one of the two relative steering angles, and, where one of the two relative steering angle detectors is determined as outputting the one of the two relative steering angles, update the latest absolute steering angle by adding outputted one of the two relative steering angles to the stored latest absolute steering angle.
