The sensor allows you to inform the transmission ECU about the pressure of the working fluid in the pressure line.
Based on this information, the ECU adjusts the pressure of the working fluid in the pressure line, based on the required value. Pressure correction is carried out by means of a solenoid valve for modulating the pressure in the pressure line (EVM pressure).
The sensor consists of stress-sensitive elements deformed under the action of pressure of the working fluid.
