Fuel Temperature Sensor
• The fuel temperature sensor is installed on the fuel intake side and utilizes the characteristics of a thermistor in which
the electric resistance changes with the temperature in order to detect the fuel temperature.
Check Valve
• The check valve, which is located between the SCV (Suction Control Valve) and the pumping mechanism, prevents
the pressurized fuel in the pumping mechanism from flowing back into the SCV.
Check Valve Open
- During fuel suction (SCV ON), the feed pressure opens the valve, allowing fuel to be drawn into the pumping mech-
anism.
Check Valve Closed
- During fuel pumping (SCV OFF), the pressurized fuel in the pumping mechanism closes the valve, preventing fuel
from flowing back into the SCV.
