The fuel system uses an electronic returnless system. The system comprises a fuel pump module mounted in the fuel tank to deliver Low Pressure (LP) fuel at variable flow to the fuel charging and control system on the engine. Fuel pump operation is regulated by a Fuel Pump Driver Module (FPDM) which is controlled by the Engine Control Module (ECM). The FPDM regulates the flow and pressure supplied by controlling the operation of the fuel pump using a Pulse Width Modulation (PWM) output. A LP fuel system - fuel pressure sensor is located in the fuel supply line to the engine and is monitored by the ECM for fuel pump control.
Two fuel level sensors are installed in either side of the fuel tank. The sensors are a Magnetic Passive Position Sensor (MAPPS) which provide a variable resistance to ground for the output from the fuel gauge.
The fuel system also incorporates an Evaporative Emission (EVAP) system which is part of the On-board Refueling Vapor Recovery (ORVR) feature. The function and operation of the system is designed to meet EVAP requirements to minimize fuel vapor losses.
