Fuel System - General Information
Overview
Fuel System
3.5L Ti-VCT
The fuel system:
- is a 2-speed MRFS with sequential MFI.
- uses a dual-container (saddle-type) fuel tank.
- has a fuel level sensor assembly.
- has a FP module that operates on 10 or 12 volts depending on load, that supplies fuel under pressure to the fuel rail.
- has a lifetime fuel filter (serviced as part of the FP module).
- has an Easy Fuel™ fuel tank filler pipe assembly, which cannot be modified in any way and is serviced only by the installation of a new fuel tank filler pipe assembly.
- has a supplemental refueling adapter located in the spare tire compartment.
- has a FP control module located behind the RH C-pillar trim panel.
- has fuel tubes (liquid and vapor) along with brake tubes mounted on the underside of the vehicle in a bundle.
- has a FTP sensor (part of the fuel vapor tube assembly).
- uses separately controlled fuel injectors for each cylinder. The fuel injectors are mounted to the intake manifold and are supplied with pressurized fuel from the FP module to the fuel rail.
- fuel rail pressure is controlled by the electronic FP module which is enabled by the PCM.
- has a serviceable fuel level sender mounted on the FP module.
- has a serviceable fuel level sender mounted on the fuel level sensor assembly.
Fuel System
2.0L GDTI, 3.5L GDTI
The fuel system:
- is a variable speed Closed Loop Pressure Control (CLPC) Fuel System with GTDI.
- uses a dual-container (saddle-type) fuel tank.
- has a fuel level sensor assembly.
- has a FP module that operates on 5.5 or 12 volts depending on load, that supplies fuel under pressure to the high pressure FP.
- has a lifetime fuel filter (serviced as part of the FP module).
- has an Easy Fuel™ fuel tank filler pipe assembly, which cannot be modified in any way and is serviced only by the installation of a new fuel tank filler pipe assembly.
- has a supplemental refueling adapter located in the spare tire compartment.
- has a high pressure FP that supplies high pressure, low volume fuel pressure to the fuel rails.
- has a FP control module located behind the RH C-pillar trim panel.
- has fuel tubes (liquid and vapor) along with brake tubes mounted on the underside of the vehicle in a bundle.
- has a high pressure fuel tube from the high pressure FP to the fuel rails.
- has a FRP sensor on the LH fuel rail.
- has a FTP sensor (part of the fuel vapor tube assembly).
- uses separately controlled fuel injectors for each cylinder. The fuel injectors are mounted to the intake manifold and are supplied with pressurized fuel from the FP module to the fuel rail.
- fuel rail pressure is controlled by the electronic FP module which is enabled by the PCM.
- has a serviceable fuel level sender mounted on the FP module.
- has a serviceable fuel level sender mounted on the fuel level sensor assembly.
FP Shut-off Feature
In the event of a moderate to severe collision, the vehicle is equipped with a FP shut-off feature that is initiated by the event notification signal.
Should the vehicle shut off after a collision due to this feature, the vehicle may be restarted by first turning the ignition to the OFF position and then turning the ignition to the ON position. In some instances the vehicle may not start the first time and may take one additional ignition cycle.
