The invention disclosed is a steering system providing steered wheel angle sensing for vehicles having a spaced pair of steered wheels, a two-way hydraulic steering cylinder operatively connected to the steered wheels, and a hydraulic circuit connected to the cylinder. The invention includes a hydraulic two-way valve, a hydraulic pump for supplying fluid under pressure to the circuit and being hydraulically connected to the valve, the cylinder having a single moveable shaft therein to move, in opposite directions to steer the wheels in one of two angular directions, a hydraulic motor in the circuit between the cylinder and the valve, an output shaft on the motor adapted to rotate in one of two directions depending on the direction of flow of fluid through the motor, and a pair of sensors adjacent the shaft to determine the direction of motion of the shaft, and hence an angular steering position of the wheels.
