CHECK CHART FOR RESISTANCE AND CONTINUITY
BETWEEN TERMINALS

1.

Turn the ignition switch to OFF.

2.

Disconnect the engine-ECU connector.

3.

Measure the resistance and check for continuity between
the terminals of the engine-ECU harness-side connector
while referring to the check chart.

NOTE
(1) When measuring resistance and checking continuity,

a harness for checking contact pin pressure should
be used instead of inserting a test probe.

(2) Checking need not be carried out in the order given

in the chart.

Caution
If the terminals that should be checked are mistaken,
or if connector terminals are not correctly shorted
to earth, damage may be caused to the vehicle wiring,
sensors, engine-ECU and/or ohmmeter.
Be careful to prevent this!

4.

If the ohmmeter shows any deviation from the standard
value, check the corresponding sensor, actuator and
related electrical wiring, and then repair or replace.

5.

After repair or replacement, recheck with the ohmmeter
to confirm that the repair or replacement has corrected
the problem.

ON-VEHICLE SERVICE

Caution
(1) Never attempt to tamper the fixed SAS. The fixed SAS

is precisely adjusted at factory.

(2) Should it be tampered, the full closed position of the

throttle valve will be changed. This causes the
engine-ECU to learn a wrong position of the throttle
valve.

FUEL PRESSURE TEST

MEASUREMENT OF FUEL LOW PRESSURE BETWEEN
FUEL PUMP (LOW PRESSURE) AND FUEL PUMP
(HIGH PRESSURE)

1.

Release residual pressure from the fuel pipe line to prevent
fuel gush out.

NOTE
Refer to the ’00 PAJERO PININ Workshop Manual (Pub.
No. CKRE00E1) GROUP 13A – On-vehicle Service.

2.

Disconnect the high-pressure fuel hose at the fuel pump
(high pressure) side.

Caution
Cover the hose connection with rags to prevent splash
of fuel that could be caused by some residual pressure
in the fuel pipe line.

3.

Remove the union joint and bolt from the special tool
(adapter hose) and instead attach the special tool (hose
adapter) to the adapter hose.

4.

Install the special tool (for measuring the fuel pressure)
that was set up in step 3.

<When using the fuel pressure gauge set (special tool)>
(1) Install the special tool (for measuring the fuel pressure)

between the high-pressure fuel hose and the fuel pump
(high pressure).

(2) Install the fuel pressure gauge set (special tool) on

the special tool (for measuring the fuel pressure)
putting the gasket between them.

(3) Connect the lead wire of the fuel pressure gauge set

(special tool) to the power supply (cigarette lighter
socket) and to the MUT-
