Circuit Description
WARNING: This page is about a different car, the 2002 Nissan Sentra, 2002 Infiniti G20, 2001 Nissan Sentra, and 2001 Infiniti G20. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
Line pressure duty cycle is not consistent when closed throttle position switch is on. To confirm line pressure, duty cycle at low throttle pressure should be opened until closed throttle position switch is off.
The line pressure solenoid regulates oil pump pressure to match driving conditions in response to signal sent from TCM.
