Checking Exhaust System

NLFE0010

Check

exhaust

pipes,

muffler

and

mounting

for

improper

attachment, leaks, cracks, damage, chafing or deterioration.

Removal and Installation

NLFE0005

CAUTION:

Always replace exhaust gaskets with new ones when
reassembling.

With engine running, check all tube connections for
exhaust gas leaks, and entire system for unusual noises.

Check to ensure that mounting brackets and mounting
insulators are installed properly and free from undue
stress. Improper installation could result in excessive
noise or vibration.

Discard any heated oxygen sensor which has been
dropped from a height of more than 0.5 m (19.7 in) onto a
hard surface such as a concrete floor; use a new one.

Before installing a new oxygen sensor, clean exhaust sys-
tem threads using oxygen sensor thread cleaner tool and
apply anti-seize lubricant.

Do not overtorque the oxygen sensor. Doing so may
cause damage to the oxygen sensor, resulting in the MI
coming on.

Be sure to use genuine exhaust system parts which are
designed

especially

for

heat

resistance,

corrosion

resistance, and shape.

Perform the operation with the exhaust system fully
cooled down because the system will be heated just after
the engine stops.

Be careful not to cut your hand on the insulator edge.

CAUTION:

Do not disassemble the accelerator pedal assembly. Do not remove the sensors and the switches
from the assembly.

Avoid impact from dropping etc. during handling.

Be careful to keep the assembly away from water.

Do not adjust the adjusting screw (painted white) of the accelerator work unit.

When the connector of the accelerator sensor is disconnected, reconnect the connector, and touch
“CLEAR” in “OFF ACCEL PO SIG” of the active test using the CONSULT-II. Or, warm up the engine,
then leave it idling for approximately 10 minutes.

NFE067

Inspection

NLFE0020

Check that the accelerator pedal moves smoothly within the
whole operation range.

Check that the accelerator pedal securely returns to the origi-
nal position.

Check that the drum of the accelerator work unit can be fully
opened.

Refer to EC-1113, “Basic Inspection” for the inspection of the
accelerator work unit and the accelerator pedal switch.

INSTALLATION

NLFE0021S02

Install in the reverse order of removal.

Replace the O-ring of the fuel level warning sensor with a new
one.

Tighten the fuel filter so that the sealing face contacts the
packing, then retighten it manually by approximately 2/3 turn.

After installation, operate the priming pump vertically to per-
form air bleeding.
Refer to FE-16, “Bleeding Fuel Filter”.

Bleeding Fuel Filter

NLFE0023

After the repair, bleed air from the piping by pumping the prim-
ing pump up and down until it becomes heavy.

To start the engine, rotate the starter for a maximum of 30
seconds.
To start the engine more quickly, crank the engine while pump-
ing the priming pump (requires two workers).

If the engine does not start after rotating the starter for a maxi-
mum of 30 seconds, stop it once, and pump the priming pump
again until it becomes heavy.

Rotate the starter again until the engine starts running.

After the engine starts, let it idle for at least 1 minute to stabi-
lize the behavior.

When air is bled completely, the pumping of the priming
pump suddenly becomes heavy. Stop the operation at that
time.

If it is difficult to bleed air by the pumping of the priming
pump (the pumping of the priming pump does not become
heavy), disconnect the fuel supply hose between the fuel
filter and the injection pump. Then, perform the operation
described above, and make sure that fuel comes out. (Use
a pan, etc. so as not to spill fuel. Do not let fuel get on
engine and other parts.) After that, connect the hose, then
bleed air again.

Start engine and let it idle for at least one minute after
performing air bleeding.

Disconnect fuel return hose.

Place a suitable container beneath hose end.
