Low Fuel Pressure Sensor -G410-, Checking: Notes

GENERAL DESCRIPTION 

The low-side fuel pressure is constantly monitored by the Low Fuel Pressure Sensor -G410- and sent to the Engine Control Module -J623-. If this pressure deviates from the desired pressure, the Engine Control Module -J623- sends a signal to the Fuel Pump Control Module -J538-. The Fuel Pump Control Module -J538- then sends a PWM signal to the Transfer Fuel Pump -G6- until the desired fuel pressure is achieved.
