INTRODUCTION
NOTE: Unless stated otherwise in testing procedures, perform all
voltage tests using a Digital Volt-Ohmmeter (DVOM) with a
minimum 10-megohm input impedance. Voltage readings may vary
slightly due to battery condition or charging rate.
Pin voltage charts are supplied to reduce diagnostic time.
Checking pin voltages at the PCM connector determines whether it is
receiving and transmitting proper voltage signals. Diagnostic charts
may also help determine if PCM harness is shorted or open.
TEST PROCEDURE
CAUTION: Shorting positive DVOM lead between connector terminal and
ground could damage vehicle wiring, sensor and PCM.
1) If necessary, remove Powertrain Control Module (PCM) to
access harness connector. For PCM location, see PCM LOCATION table.
Leave PCM connectors connected.
2) Using DVOM, backprobe terminals. Connect positive DVOM
lead to appropriate PCM terminal. Connect negative DVOM lead to PCM
ground terminal. For PCM terminal identification, see appropriate
chart. See Figs. 1-24.
3) All measurements are applicable to vehicle at normal
operating temperature at sea level. Unless otherwise noted, engine is
idling when specification requires engine running. Ensure transmission
shift selector is in Neutral or Park (as applicable). If DVOM displays\
measurement that is not within specification, see G - TESTS W/CODES
article.

METRIC CONVERSIONS
1998 Mitsubishi Montero
GENERAL INFORMATION
METRIC CONVERSIONS
METRIC CONVERSIONS
Metric conversions are making life more difficult for the
mechanic. In addition to doubling the number of tools required,
metric-dimensioned nuts and bolts are used alongside English
components in many new vehicles. The mechanic has to decide which tool
to use, slowing down the job. The tool problem can be solved by trial
and error, but some metric conversions aren't so simple. Converting
temperature, lengths or volumes requires a calculator and conversion
charts, or else a very nimble mind. Conversion charts are only part of
the answer though, because they don't help you "think" metric, or
"visualize" what you are converting. The following examples are
intended to help you "see" metric sizes:
LENGTH
Meters are the standard unit of length in the metric system.
The smaller units are 10ths (decimeter), 100ths (centimeter), and
1000ths (millimeter) of a meter. These common examples might help you
to visualize the metric units:
* A meter is slightly longer than a yard (about 40 inches).
* An aspirin tablet is about one centimeter across (.4 inches).
* A millimeter is about the thickness of a dime.
VOLUME
Cubic meters and centimeters are used to measure volume, just
as we normally think of cubic feet and inches. Liquid volume
measurements include the liter and milliliter, like the English quarts
or ounces.
* One teaspoon is about 4 cubic centimeters.
* A liter is about one quart.
* A liter is about 61 cubic inches.
WEIGHT
The metric weight system is based on the gram, with the most
common unit being the kilogram (1000 grams). Our comparable units are
ounces and pounds:
* A kilogram is about 2.2 pounds.
* An ounce is about 28 grams.
TORQUE
Torque is somewhat complicated. The term describes the amount
of effort exerted to turn something. A chosen unit of weight or force
is applied to a lever of standard length. The resulting leverage is
called torque. In our standard system, we use the weight of one pound
applied to a lever a foot long, resulting in the unit called a foot-
pound. A smaller unit is the inch-pound (the lever is one inch long).
Metric units include the meter kilogram (lever one meter long
with a kilogram of weight applied) and the Newton-meter (lever one

oil leakage from turbocharger assembly. Check for proper wastegate
valve operation. See I - SYSTEM/COMPONENT TESTS article.
CAUTION: Apply light coat of oil to inner surface of flared area on
water pipe (flare nut fitting) before connecting to engine.
Installation (All Models)
1) To install, reverse removal procedure. Before oil pipe
flare nut (above turbocharger) is installed, pour clean engine oil
into turbocharger oil pipe installation hole. Ensure oil and air hoses
are properly installed and securely clamped.

terminals. See Fig. 1. Select 10-amp scale.
3) Turn off all electrical accessories. Turn off interior
lights, underhood lamp, trunk light, illuminated entry, etc. To avoid
damaging ammeter or obtaining a false meter reading, all accessories
must be off before turning test switch knob to OFF position.
4) Turn test switch knob to OFF position to allow current to
flow through ammeter. If meter reads wrong polarity, turn test switch
to ON position and reverse leads. Turn test switch to OFF position.
Observe current reading. If reading is less than 2 amps, turn test
switch to ON position to keep electrical circuits powered-up.
5) Select low amp scale. Switch lead to the correct meter
position. Turn test switch to OFF position and compare results to
normal current draw. See the GENERAL MOTORS PARASITIC LOAD TABLE . If
current draw is unusually high for the vehicle's overall electrical
system, remove system fuses one at a time until current draw returns
to normal.
6) Turn test switch to ON position each time door is opened
or fuse is removed. Turn switch to OFF position to read current draw
value through meter. When the cause of excessive current drain has
been located and repaired, remove test switch and reconnect negative
battery cable to the negative battery terminal.
