Control solenoid valve, task - GF27.19-P-5111-01A
Transmission 722.9 in model 171.4, 203, 209, 211, 215, 219, 220, 230, 463.303/340/341 working pressure control solenoid valve
The working pressure control solenoid valve (VGS) (Y3/8y1) is actuated by the fully integrated transmission control (VGS) control unit (Y3/8n4) and influences the position of the working pressure regulating valve. The working pressure depends on the regulating valve position and thus on the geometry of the working pressure regulating valve.
The working pressure control solenoid valve (VGS) (Y3/8y1) has a lowering characteristic. This means that the oil pressure applied in the working pressure regulating valve reduces as the actuating current increases. In limp-home mode of the fully integrated transmission control (VGS) all the control solenoid valves are de-energized. The working pressure control solenoid valve (VGS) (Y3/8y1) thus supplies maximum pressure.
