Refer to the system diagram to see a functional layout
of the system.
The EGR valve lowers peak combustion temperatures
and reduces oxides of nitrogen emissions (NOx) by
recirculating exhaust gas through the intake manifold
and into the combustion chambers.
Refer to the system diagram to see a functional layout
of the system.
The EVAP canister temporarily stores fuel vapor from
the fuel tank until it can be purged back into the engine
and burned.
When the engine coolant temperature is below 60 °C
(140 °F), the ECM/PCM turns off the EVAP canister
purge valve which cuts vacuum to the EVAP canister. The FTP sensor converts fuel tank absolute pressure
into an electrical input to the ECM/PCM.
The EVAP canister vent shut valve is on the EVAP
canister.
The EVAP canister vent shut valve controls the venting
of the EVAP canister.

1. Temporarily attach a new base gasket (A) to the
fuel tank unit (B), then insert the fuel tank unit
partially into the fuel tank.
NOTE: Be careful not to damage the new base gasket.
 Be careful not to bend the fuel gauge sending unit.
 Do not coat the base gasket with oil. 2. Transfer the base gasket (A) from the fuel tank unit
to the fuel tank.
3. Align the marks (B) on the fuel tank and the fuel tank unit, then insert the fuel tank unit into the fuel
tank until it sits on the base gasket.
NOTE: To prevent a fuel leak, check the base gasket,
visually or by hand, to make sure it is not pinched.

4. Install a locknut plate (A) and a new locknut (B).
5. Using the special tool, tighten the new locknut (A) to the specified torque.
NOTE: After tightening, make sure the marks are still aligned.
 After installation, check the base gasket, visually or by hand, to make sure it is not pinched. 6. Connect the fuel tank unit 4P connector, then
connect the quick-connect fitting.
7. Reconnect the negative cable to the battery, and turn the ignition switch to ON (II) (but do not
operate the starter motor). The fuel pump will run
for about 2 seconds, and fuel pressure will rise.
Repeat this two or three times, then check that
there is no leakage in the fuel supply system.
8. Install the access panel (A) to the floor.
9. Install the rear floor upper cross-member (A).
10. Install the rear seat cushion (see page 20-131).
11. Install the fuel fill cap.
