3) Using scan tool, read Fuel Tank Differential Pressure
(FTDP) sensor (item 73). Using hand-held pressure/vacuum pump, apply\
0.42 psi. If scan tool reading reaches 0.42 psi, go to next step. If
reading does not reach 0.42 psi, go to step 8).
4) Disconnect EVAP canister purge hose. Connect Purge Flow
Indicator (MB995061) between EVAP canister and disconnected hose. Turn\
engine on and allow it to reach operating temperature. Turn all lights
and accessories off. Place transmission in Park or Neutral. Observe
purge flow indicator while increasing engine RPM several times. If
purge flow indicator reads less than 2.5 SCFH (20 cm(3)/sec), check
EVAP canister purge hose and EVAP canister port for clogging. If hose
and port are okay, check EVAP purge solenoid. See DTC P0443. If
solenoid is okay, replace EVAP canister. Go to step 20).
5) Using scan tool, read Engine Coolant Temperature (ECT)
sensor temperature (item 21). Compare scan tool reading with
temperature gauge reading. If readings are about the same, go to next
step. If readings are not about the same, go to DTC P0115 test.
6) Using a thermometer, check engine compartment ambient
temperature. Using scan tool, read Intake Air Temperature (IAT) sensor\
temperature (item 13). Compare IAT sensor and thermometer readings. If\
readings are not about the same, go to DTC P0110 test. If readings are
about the same, go to next step.
7) Using scan tool, read Power Steering Pressure (PSP) switc\
h
status (item 27). Switch status should read ON when steering wheel is

10) Disconnect hand-held pressure/vacuum pump from "T"
fitting. Install an evaporative emission system tester in place of
vacuum held pump and apply 0.49 psi. Wait two minutes. If pressure
drops less than 0.20 psi, go to next step. If pressure drops 0.29 psi
or more, go to step 13).
11) Disconnect EVAP purge solenoid-to-EVAP canister hose at
EVAP canister. Connect hand-held pressure/vacuum pump to hose and
apply 0.9 psi. If pressure is not maintained, check EVAP purge
solenoid for leak. If EVAP purge solenoid is okay, replace hose. Go to
step 24). If pressure is maintained, go to next step.
12) Disconnect EVAP vent solenoid-to-EVAP canister hose at
EVAP canister. Connect hand-held pressure/vacuum pump to hose and
apply 0.9 psi. If pressure is not maintained, check EVAP vent solenoid
for leak. If EVAP vent solenoid is okay, replace hose. Go to step 20).

WARNING: R-134a service equipment or vehicle A/C systems SHOULD NOT
be pressure tested or leak tested with compressed air. Some
mixtures of air/R134a have shown to be combustible at
elevated pressures. These mixtures are dangerous and may
cause fire and/or explosions. See AIR CONDITIONING SERVICE
article in GENERAL INFORMATION section.
AIR CLEANER FILTER
WARNING: Operating the engine with the air cleaner off can cause you
or others to be burned. The air cleaner not only cleans the
air, it stops flame if the engine backfires. Do not drive
with it off, and be careful working on the engine with the
air cleaner off.
ANTI-LOCK BRAKE SYSTEM
The anti-lock brake system contains electronic equipment that
can be susceptible to interference caused by improperly installed or
high output radio transmitting equipment. Since this interference
could cause the possible loss of the anti-lock braking capability,
such equipment should be installed by qualified professionals.
On models equipped with anti-lock brake systems, ALWAYS
observe the following cautions:
* DO NOT attempt to bleed hydraulic system without first
referring to the appropriate ANTI-LOCK BRAKE SYSTEM article
in the BRAKES Section.
* DO NOT mix tire sizes. As long as tires remain close to the
original diameter, increasing the width is acceptable.
Rolling diameter must be identical for all 4 tires. Some
manufacturers recommend tires of the same brand, style and
type. Failure to follow this precaution may cause inaccurate
wheel speed readings.
* Use ONLY recommended brake fluids. DO NOT use silicone brake
fluids in an ABS-equipped vehicle.
AUTOMATIC TRANSAXLE SERVICE
WARNING: Make certain that no fluid is spilled when the transaxle
fluid is inspected, or when fluid is added soon after
driving (since the engine is hot). If the fluid spills onto
the exhaust manifold, there is danger of fire.
BATTERY SERVICE
WARNING: When battery is disconnected, vehicles equipped with
computers may lose memory data. When battery power is
restored, driveability problems may exist on some vehicles.
These vehicles may require a relearn procedure. See COMPUTER
RELEARN PROCEDURES article in GENERAL INFORMATION section.
WARNING: Batteries produce flammable hydrogen gas. Keep flames and
sparks away from the battery or and explosion may occur.
Never smoke when working in the vicinity of the battery.
WARNING: When checking or servicing the battery, disconnect the
negative cable. Be careful not to cause a short circuit by

Mitsubishi Maintenance & Service Intervals
Mitsubishi: Montero
* READ THIS FIRST *
Before preforming maintenance on vehicle, ensure that all
cautions and warnings have been observed to prevent vehicle damage or
personal injury. See CAUTIONS & WARNINGS in MAINTENANCE INFORMATION
article in this section.
Introduction
The frequency of scheduled inspection and maintenance
services in this article are based on "normal" vehicle usage. They DO
NOT take into account the following "severe" conditions:
* Driving In Dusty Conditions
* Trailer Towing, Police, Taxi, commercial Type Operation
* Extensive Idling, Driving In Stop-And-Go Traffic
* Short Trip Operation At Freezing Temperatures (Engine Not
Thoroughly Warmed Up)
* Driving In Sandy Areas
* Driving In Salty Areas
* More Than 50% Operation In Heavy City Traffic Or At Sustained
High Speeds During Hot Weather Above 90
F (32C)
* Driving On Off-Road
If any of these severe conditions exist, the "normal" service
schedule frequency for some service items is inadequate and must be
supplemented. See the following section for specific details,
SEVERE SERVICE CONDITIONS/ACTIONS .
SEVERE SERVICE CONDITIONS/ACTIONS
The following table identifies eight "severe" conditions that
cause faster-than-normal wear. Each condition lists affected service
item(s) and their revised (more frequent) service interval.
If any severe condition(s) is applicable, its revised service\
interval(s) supersede those found in the "normal" schedules. Depending\
on the specific mileage/time, the revised interval(s) may overlap a
normal schedule (in which case they can be done together). If not, it
must be performed outside of the normal schedule.
