Line Pressure Switch
WARNING: This page is about a different car, the 2003 Nissan Pathfinder. However, it is still accessible from the selected car via links, so may be relevant.
- With the transfer system design, control of the oil pressure provides the transmission of drive torque to the front wheels. The main pressure to control the oil pressure is referred to as the line pressure.
The line pressure switch determines whether or not adequate line pressure has built up under different operating conditions.
- The line pressure switch turns ON when line pressure is produced.
- The line pressure switch senses line pressure abnormalities and turns the 4WD warning lamp ON.
