POWER STEERING SYSTEM GENERAL

  1. OUTLINE

    1. A rack and pinion type steering gear with a hydraulic power steering assist is used.

    2. A Variable Flow Control (VFC) power steering is used on all models except models with 5L-E engine.

  3. MAIN FEATURES

    1. Variable Flow Control (VFC) Power Steering

      1. The VFC power steering is provided with a solenoid valve, which is controlled by the power steering ECU, in the vane pump.

      2. The solenoid valve controls the discharge flow rate of the power steering fluid in accordance with the operating conditions of the steering wheel, vehicle speed, engine speed and transfer drive mode. Thus, it reduces the load on the engine applied by the actuation of the vane pump, and improves fuel economy.
