Fuel System
Fuel System
2.0L Gasoline Turbocharged Direct Injection (GTDI)
Fuel System
The fuel system consist of:
- an Front Wheel Drive (FWD) L-shaped fuel tank.
- fuel, vapor and brake tubes in an integrated bundle assembly.
- quick connect fuel and vapor tube couplings.
- a fuel tank filler pipe assembly, which cannot be modified in any way, that also contains a restrictor plate to permit only unleaded fuel to be pumped into the tank.
- Easy Fuel(TM) (capless) fuel tank filler pipe assembly.
- an Fuel Pump Control Module (FPCM).
- a Mechanical Returnless Fuel System (MRFS).
- a Fuel Pump (FP) module containing:
- the electric FP (Fuel Pump) module which provides pressurized fuel to the high pressure Fuel Pump (FP).
- the fuel level sensor.
- a check valve which maintains system pressure after the pump is shut off.
- a pressure relief for overpressure protection in the event of restricted airflow.
- a fuel filter providing filtration to protect the fuel injectors from foreign material.

Fuel System
The fuel system consist of:
- an All-Wheel Drive (AWD) saddle-type or Front Wheel Drive (FWD) L-shaped fuel tank.
- fuel, vapor and brake tubes in an integrated bundle assembly.
- quick connect fuel and vapor tube couplings.
- a fuel tank filler pipe assembly, which cannot be modified in any way, that also contains a restrictor plate to permit only unleaded fuel to be pumped into the tank.
- Easy Fuel(TM) (capless) fuel tank filler pipe assembly.
- an Fuel Pump Control Module (FPCM).
- a Mechanical Returnless Fuel System (MRFS).
- a Fuel Pump (FP) module containing:
- the electric FP (Fuel Pump) module which provides pressurized fuel to the engine.
- the fuel level sensor.
- a check valve which maintains system pressure after the pump is shut off.
- a pressure relief for overpressure protection in the event of restricted airflow.
- a fuel filter providing filtration to protect the fuel injectors from foreign material.
The AWD (All-Wheel Drive) vehicles have 2 fuel level sensors, one mounted on the FP (Fuel Pump) module located in the LH side of the fuel tank and a separate fuel level sensor located in the RH side of the fuel tank.
Fuel System Shutoff Feature
In the event of a moderate to severe collision, the vehicle is equipped with a Fuel Pump (FP) shut-off feature that is initiated by the event notification signal.
The event notification signal is a signal provided by the Restraints Control Module (RCM) to the Fuel Pump Control Module (FPCM). The FPCM (Fuel Pump Control Module) will then shut-off power to the FP (Fuel Pump) module. The RCM (Restraints Control Module) will also send a fuel shut-off signal to the Powertrain Control Module (PCM). The PCM (Powertrain Control Module) will then send a signal to the FPCM (Fuel Pump Control Module) to shut-off the FP (Fuel Pump) module.
Should the vehicle shut-off after a collision due to this feature, the vehicle may be restarted by first turning the ignition switch to the OFF position and then turn the ignition switch to the ON position. In some instances the vehicle may not start the first time and may take one additional key cycle.
