P0795 AXIS A FEED PRESSURE SOLENOID VALVE

TRANSMISSION: GR6Z30A

P0795

Description


  • The axis A feed pressure solenoid valve is installed on the actuator control module and builds up the source pressure for the gear operation actuators for even number gears and for the clutch A pressure solenoid valve based on the signals from TCM. The solenoid valves adjust the source pressure to drive the gears and clutches.
  • The axis A feed pressure solenoid valve is an N/L type (normal low) in which no control oil pressure is built up when no current flows through the coil.
