FUEL SUPPLY - General Information/On-vehicle Service13B-2
GENERAL INFORMATION
DThe steel fuel tank is located under the floor of the rear seats to provide increased safety and increase
the amount of luggage compartment space.
DThe fuel tank has been equipped with a valve assembly which incorporates a fuel cut-off valve to
prevent fuel from leaking out in the event of a collision for adjusting the pressure inside the fuel
tank.
DThe fuel pump module contains a fuel pump, fuel filter, and fuel pressure regulator.

FUEL PUMP AND GAUGE ASSEMBLY (FUEL
PUMP)
1. FUEL PUMP OPERATION CHECK
Refer to GROUP 13A - On-vehicle service
2. FUEL PUMP REPLACEMENT
(1) Remove the rear seat cushion assembly.
(Refer to GROUP 52A.)
(2) Remove the service hole cover.
(3) Disconnect the harness connector, high-pressure fuel
tube, suction hose and return hose.
(4) Unscrew the mounting nuts to remove the fuel pump
and gauge assembly.
(5) Replace the fuel pump. (Refer to P.13B-7.)
(6) Install the fuel pump and gauge assembly. Tighten
the mounting nuts to the specified torque.
Specified torque: 2.5± 0.5 N·m
(7) Connect the harness connector, high-pressure fuel
tube, suction hose, and return hose.
Caution
1) Snap the high-pressure fuel hose or suction
hose one-touch joint into place, then pull back
slightly on the hose to assure it is securely
fitted. However, the connection should have
a play of approx. 3 mm.
2) Insert the return hose for 20 - 30 mm for
connection.
(8) Install the service hole cover.
(9) Install the rear seat cushion assembly.

INTAKE AND EXHAUST -General Information15-2
GENERAL INFORMATION
SUPERCHARGING PRESSURE CONTROL
By controlling the duty of the waste gate solenoid valve, the waste gate actuator functions to control the supercharging
pressure. This allows a supercharged pressure matching the engine operation state to be attained. Control is carried
out to prevent excessive supercharging and thereby prevent engine damage.
SECONDARY AIR CONTROL
When decelerating during high-speed travel, the secondary air is introduced into the upstream of the turbocharger
to prevent the turbine speed from dropping and to increase the acceleration responsiveness after deceleration.
The secondary air is introduced into each cylinder of the exhaust manifold to maximize the effect.

ENGINE ELECTRICAL -Ignition System16-26
IGNITION SYSTEM
GENERAL INFORMATION
This system is equipped with two ignition coils (A
and B) with built-in power transistors for the No.
1 and No. 4 cylinders and the No. 2 and No. 3
cylinders respectively.
Interruption of the primary current flowing in the
primary side of ignition coil A generates a high
voltage in the secondary side of ignition coil A.
The high voltage thus generated is applied to the
spark plugs of No. 1 and No. 4 cylinders to generate
sparks. At the time that the sparks are generated
at both spark plugs, if one cylinder is at the
compression stroke, the other cylinder is at the
exhaust stroke, so that ignition of the compressed
air/fuel mixture occurs only for the cylinder which
is at the compression stroke.
In the same way, when the primary current flowing
in ignition coil B is interrupted, the high voltage
thus generated is applied to the spark plugs of
No. 2 and No. 3 cylinders.
The Engine-ECU turns the two power transistors
inside the ignition coils alternately on and off. Thiscauses the primary currents in the ignition coils
to be alternately interrupted and allowed to flow
to fire the cylinders in the order 1-3-4-2.
The Engine-ECU determines which ignition coil
should be controlled by means of the signals from
the camshaft position sensor which is incorporated
in the camshaft and from the crank angle sensor
which is incorporated in the crankshaft. It also
detects the crankshaft position in order to provide
ignition at the most appropriate timing in response
to the engine operation conditions. It also detects
the crankshaft position in order to provide ignition
at the most appropriate timing in response to the
engine operation conditions.
When the engine is cold or operated at high
altitudes, the ignition timing is slightly advanced
to provide optimum performance.
When the automatic transmission shifts gears, the
ignition timing is also retarded in order to reduce
output torque, thereby alleviating shifting shocks.
