5. Switch on and off the VVT
solenoid valve. Clean the valve
with an air gun and repeat 2-3
times.
Note: Each time switch the valve on no
longer than 2 seconds, otherwise the
VVT solenoid valve may be damaged.

2.3.2 Description and Operation
2.3.2.1 Description and Operation
The fuel supply system provides a suitable amount of fuel to the engine in a variety of operating
conditions. The fuel is sprayed into the engine through the fuel injectors. Fuel tank stores fuel. An
electric fuel pump is installed in the fuel tank and it will pump fuel into the fuel distributing pipe
assembly. Fuel pump provided fuel pressure exceeds the pressure needed by fuel injectors. Fuel
pressure regulator is part of the fuel pump assembly, which keeps fuel supplied to the fuel
injectors is under specified pressure. This vehicle fuel system has no fuel return system.
1. Fuel
Tank
Fuel tank is made from high-density polypropylene vinyl and other materials. Two metal straps
attached to the underbody are used to fasten it in place. And it has a fuel vapor ventilation valve
with roll-over protection function.
2. Fuel Tank Filling Cap
Note: In the need for replacing the fuel tank filler cap, use a fuel tank filler cap with the same
function as the original one. If the fuel tank filler cap is not correctly installed, it could cause
serious fuel system faults.
The fuel tank filling tube filler cover is equipped with a screw thread structure, which allows air
coming in once it is turned loose. It uses the structure of the ratchet in order to prevent
over-tightening. Ventilation function means the fuel tank internal pressure can be released before
dismantling the cap from the vehicle. Instructions are attached to the cap. The filler cap also
integrates a security vacuum pressure limiting valve.
3. Fuel
Pump
Electric fuel pump is a modular fuel turbo pump located inside the fuel tank. Electric fuel pump is
controlled by the engine control module (ECM) through the fuel pump relay. Electric fuel pump
will start providing fuel 2s in advance to ensure that the fuel pressure achieve the requirements of
the normal system operation. The fuel pump resistance range is 0.2~3.0 Ω. This model comes with
electric fuel pump fuel storage in order to prevent the fuel level too low or provide fuel supply in
harsh operating conditions.
4. Fuel Pressure Regulator Assembly
Fuel pressure regulator is integrated in the fuel pump assembly. Fuel pressure regulator's main
function is to regulate the fuel pipe fuel flow and to control the fuel injectors pressure. When the
ignition switch is at ON position and the engine is shut down, the system fuel pressure should be
about 400 kPa.
5. Electric Fuel Pump Filter
As a coarse filter, the filter has the following features:
– Filters
the
pollutants.
–
Improves the electric pump service life.
If the pump output pressure is found too low, clean or replace the filter.
6. Fuel
Filter
Assembly
Fuel Filter Assembly is located at the left side of the underbody and fixed to the vehicle chassis.
The filter consists of paper filter element, which can filter the particles in the fuel may damage the
fuel system part. Fuel filter can withstand maximum fuel system pressure, temperature changes
and fuel additive effect.
7. Fuel Level Sensor Assembly
Fuel level sensor consists of a fuel level float, a wire arm harness assembly. The fuel level sensor
is fixed to the fuel tank. According to the location, the sliding chip provides variable resistance to
the combination instrument circuit. The resistance range is 40~250 Ω. Circuit wiring harness leads
