Exhaust System InspectionS7RS0B0206006
WARNING!
To avoid danger of being burned, do not
touch exhaust system when it is still hot.
Any service on exhaust system should be
performed when it is cool.

When carrying out periodic maintenance, or the vehicle
is raised for other service, check exhaust system as
follows:
• Check rubber mountings for damage, deterioration, and out of position.
• Check exhaust system for leakage, loose connections, dents and damages.
If bolts or nuts are loose, tighten them to specification.
• Check nearby body areas for damaged, missing or mispositioned parts, ope n seams, holes, loose
connections or other defects which could permit
exhaust fumes to seep into the vehicle.
• Make sure that exhaust system components have enough clearance from the underbody to avoid
overheating and possible damage to floor carpet.
• Any defects should be fixed at once.

Fuel Pressure Relief ProcedureS7RS0B1706003
CAUTION!
This work must not be done when engine is
hot. If done so, it may cause adverse effect to
catalyst.

NOTE
If ECM detects DTC(s) after servicing, clear
DTC(s) referring to “DTC Clearance in
Section 1A”.

1) Make sure that engine is cold.
2) Shift transaxle gear shift lever in “Neutral” (shift select lever in “P” range for A/T model), set parking
brake and block drive wheels.
3) Remove relay / fuse box cover.
4) Disconnect fuel pump relay (1) from relay / fuse box (2).
5) Remove fuel filter cap in order to release fuel vapor pressure in fuel tank, and then reinstall it.
6) Start engine and run it until engine stops for lack of fuel. Repeat cranking engine 2 – 3 times for about 3
seconds each time in order to dissipate fuel pressure
in lines. Fuel connections are now safe for servicing.
7) After servicing, connect fuel pump relay (1) to relay / fuse box and install re lay / fuse box cover.
Fuel Leakage Check ProcedureS7RS0B1706004
After performing any service on fuel system, check to
make sure that there are no fuel leakages as follows.
1) Turn ON ignition switch for 3 seconds (to operate fuel pump) and then turn it OFF.
Repeat this (ON and OFF) 3 or 4 times and apply
fuel pressure to fuel line until fuel pressure is felt by
hand placed on fuel feed hose.
2) In this state, check to see that there are no fuel leakages from any part of fuel system.
Fuel Lines On-Vehicle InspectionS7RS0B1706005
CAUTION!
Due to the fact that fuel feed line (1) is under
high pressure, use special care when
servicing it.

Visually inspect fuel lines for evidence of fuel leakage,
hose crack and deterioration or damage.
Make sure all cl amps are secure.
Replace parts as needed.
Fuel Pipe Removal and InstallationS7RS0B1706006
WARNING!
Before starting the following procedure, be
sure to observe “Precautions on Fuel System
Service” in order to reduce the risk or fire
and personal injury.

Removal
1) Relieve fuel pressure in fuel feed line according to “Fuel Pressure Relief Procedure”.
2) Disconnect negative cable at battery.
3) Disconnect fuel pipe joint and fuel hose (3) from fuel pipe (2) at the front and rear of each fuel pipe
referring to “Fuel Hose Disconnecting and
Reconnecting”.
4) Mark the location of clamps (1) on fuel pipes (2), so that the clamps can be reinstalled to where they
were.
5) Remove pipes (2) with clamp (1) from vehicle.
6) Remove clamp (1) from pipes (2).

Removal1) Remove fuel pump assembly from fuel tank referring to “Fuel Pump Assembly Removal and Installation”.
2) Disconnect main fuel level sensor connector (3).
3) With pressing snap-fit part (2), remove main fuel level sensor (1) by sliding it in the arrow direction as
shown in figure.
Installation
Reverse removal procedure for installation.Fuel Pump InspectionS7RS0B1706019
• Check fuel pump assembly for damage.
• Check fuel suction filter for evidence of dirt and contamination. If present, replace or clean and check
for presence of dirt in fuel tank.
• For electrical circuit, refer to “Fuel Pressure Check in Section 1A”.
• For inspection of main fuel level sensor (1), refer to “Fuel Level Sensor Inspection in Section 9C”.
