Steering System - Electronic: Description
The Mazda electronic power steering system is a hydraulically-assisted rack and pinion-type. This steering system changes its steering assist power according to information received from the vehicle speed sensor, turning angle sensor (steering wheel) and engine speed sensor. A control unit receives signals from these sensors and regulates hydraulic pressure. Hydraulic pressure is adjusted by a stepping motor or solenoid.
Control unit contains self-diagnostic capabilities for all electrical steering components. The control unit also includes a fail-safe function. In case vehicle speed sensor signal is not received, the control unit will use engine speed sensor signal.
