To realize the compatibility between low exhaust
emission and high engine output, an HEUI
(Hydraulically actuated Electronically controlled Unit
Injector) system, has been introduced. This system is
comprised of a hydraulic system, fuel system, and
electronic control system, using a high-pressure oil
pump in place of the conventional fuel injection pump.
The oil pressurized by means of this pump and by
signals from the ECM (Electronic Control Module)
actuates the fuel injector provided for each cylinder.
Inside of the fuel injector, fuel pressure is increased due
to the high-pressure oil. The ECM detects the driving
state of the vehicle, forms, signals sent by engine and
other part sensors, which determines the optimum fuel
injection amount and timing, thus controlling the fuel
injectors. Thus high engine output, good fuel economy,
and low exhaust emission are realized.When working on the fuel system, there are several
things to keep in mind:
1) Any time the fuel system is being worked on,
disconnect the negative battery cable except for
those tests where battery voltage is required.
2) Always keep a dry chemical (Class B) fire
extinguisher near the work area.
3) Replace all pipes with the same pipe and fittings
that were removed.
Clean and inspect “O” rings. Replace where
required.
4) Always relieve the line pressure before servicing
any fuel system components.
5) Do not attempt repairs on the fuel system until you
have read the instructions and checked the pictures
relating to that repair.
6) After maintenance work, push priming pump and
send enough fuel to the fuel system before starting
the engine.
NOTE: In comparison with the conventional engine,
the capacity of fuel passage in the 4JX1 engine is
larger. It takes the priming pump more time to fill the
engine with fuel.

REASSEMBLY
1. Clean the cartridge mounting surface of the filter
body so that the cartridge can be secured.
Apply engine oil thinly to new cartridge O-ring.
2. To facilitate bleeding, fill the new cartridge with light
oil.
3. Tighten the cartridge until O-ring comes in contact
with the seal, taking care not to spill the light oil.
4. Retighten 1/3 – 2/3 using a filter wrench.
Filter wrench: 5-8840-0203-0
Bleeding
1. Loosen air bleeding plug.
2. Operate priming pump to bleed the air in the fuel
line.
3. Operate the priming pump until the fuel is overflow
from air bleeding plug.
4. Tighten the air bleeding plug.
5. Start the engine, and if it is not started in 10
seconds or less, repeat the bleeding steps.
6. Make sure of no fuel leakage, and tighten the
priming pump.

ENGINE LUBRICATION 6G – 3
To meet a newly adopted electronically controlled fuel
injection system using engine oil two oil pumps have
been provided to increase circulating oil capacity.
The first oil pump serves mainly to lubricate the engine
parts, while the second mainly serves the fuel injectors
and partially cools the pistons.
The oil cooler is provided on the first oil pump side and
uses engine coolant.

INSPECTION AND REPAIR
1. Inspect for corrosion, wear, and breaks on the oil
cooler core.
2. If a problem is found on the oil cooler core, the oil
cooler assembly must be replaced.
INSTALLATION

OIL FILTER
REMOVAL
1. Put container under the oil filter to prevent oil from
the oil filter from flowing out.
2. Use filter wrench to remove oil filter.
Filter wrench: 5-8840-0203-0
INSTALLATION
1. Apply engine oil thinly to oil filter O-ring.
2. Tighten oil filter by hand until O-ring comes in
contact with the sealing surface.
3. Use filter wrench to tighten oil filter one turn and 1/8
turn.
4. Start engine and carefully check for oil leakage from
oil filter.
SUB OIL FILTER
The sub oil filter requires no servicing until the
replacement interval is reached.
The element is designed to provide special filtering
efficiency until it becomes due for replacement.
It is recommended to check and replace the sub oil filter
when the engine is being overhauled or if it is broken
inside the engine.
