Circuit Description
WARNING: This page is about a different car, the 2002 Infiniti QX4, 2001 Nissan Pathfinder, and 2001 Infiniti QX4. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
The line pressure duty cycle value is not consistent when the closed throttle position switch is on. To confirm the line pressure duty cycle at low pressure, the throttle should be opened until the closed throttle position switch is off.
The line pressure solenoid valve regulates the oil pump discharge pressure to suit the driving condition in response to a signal sent from the TCM.
