NOTE: Basic idle speed should only be adjusted after verifying
spark plugs, fuel injectors, idle air control motor and
engine compression are okay.
All Other Models
1) Ensure vehicle is at normal operating temperature with all
lights, cooling fan and accessories off. Shift transmission into
Neutral or Park position.
2) Basic idle speed can only be adjusted using a scan tool to
ground Data Link Connector (DLC). Connect scan tool to DLC. DLC is
located below dash, near steering column. See Fig. 2.
3) Start engine and allow it to idle. Using scan tool, select
MFI SYSTEM ACTUATOR TEST, then select item 30. Check basic idle speed.
See IDLE SPEED SPECIFICATIONS table.
CAUTION: MFI system actuator test must be cancelled or test will
continue to run for 27 minutes. Driving vehicle under this
condition may damage engine.
4) Cancel MFI system actuator test. If idle speed is not
within specification, turn engine speed adjusting screw until correct
engine speed is obtained. See Fig. 6. Access to speed adjusting screw
is obtained by removing rubber plug on throttle body.
5) If idle speed cannot be lowered by turning engine speed
adjusting screw, determine if fixed Speed Adjusting Screw (SAS). Fixed\
SAS is stop screw contacting throttle lever. See
FIXED SPEED ADJUSTING SCREW for procedure.
6) After all adjustments are verified to be correct, possible
cause of incorrect idle speed is deterioration of Idle Air Control
(IAC) circuit. See DTC P0505 in G - TESTS W/CODES article.
CURB (SLOW) IDLE SPEED
NOTE: Curb idle speed is controlled by Idle Air Control (IAC)
motor. Adjustment is usually not necessary. For curb idle
speed specifications, see IDLE SPEED SPECIFICATIONS table
under BASIC IDLE SPEED.
1) Check ignition timing and adjust if necessary. See
IGNITION TIMING . Run engine at 2000-3000 RPM for more than 5 seconds.
Allow engine to idle for 2 minutes. Check curb idle speed.
2) If curb idle speed is not within specification, check IAC
system. See DTC P0505 in G - TESTS W/CODES article. If IAC system is
okay, adjust basic idle speed. See BASIC IDLE SPEED.
FIXED SPEED ADJUSTING SCREW
NOTE: Fixed Speed Adjusting Screw (SAS) is preset by manufacturer
and usually does not require adjustment. Only adjust fixed
SAS if other adjustment procedures require it, or if

MIXTURE. Perform all adjustments with engine at normal
operating temperature, front wheels in straight-ahead
position, cooling fan and all accessories off, and
transmission in Park or Neutral.
Eclipse 2.0L Non-Turbo
1) TP sensor is not adjustable. Disconnect TP sensor
connector. Using external ohmmeter, measure resistance between TP
sensor terminals No. 1 and 3. See Fig. 8. If resistance is not 3500-
6500 ohms, replace TP sensor.
2) While slowly rotating throttle valve from idle to full
open, measure resistance between TP sensor terminals No. 2 and 3. If
resistance does not change smoothly in proportion to throttle opening,
replace TP sensor.
Montero
1) Disconnect TP sensor connector. Using jumper wires,
connect an external ohmmeter between TP sensor terminals No. 1 and 2.
See Fig. 9 . Insert .025" (.65 mm) feeler gauge between fixed speed
adjusting screw and throttle lever.
2) Loosen TP sensor mounting screws and rotate TP sensor
fully clockwise. Ensure there is continuity between terminals No. 1
and 2. Rotate TP sensor counterclockwise until there is no continuity,
and tighten screws. Install Test Harness (MB991348) between TP sensor
and harness connector.
3) Turn ignition on. Using external voltmeter, measure TP
sensor output voltage between terminals No. 1 and 3. If voltage is not
.4-1.0 volt, check harness and sensor. See DTC P0120 in G - TESTS
W/CODES article.
All Other Models
1) Disconnect TP sensor connector. Using jumper wires,
connect an external ohmmeter between TP sensor terminals No. 1 and 2
on Diamante or No. 3 and 4 on all other models. See Fig. 9. On

1) Raise and support rear axle. Place transmission in
Neutral. Apply parking brake. Rotate drive shaft clockwise. Place
reference marks on pinion dust cover and differential housing.
2) Rotate drive shaft counterclockwise, and measure distance
between reference marks. Differential must be removed and backlash
adjusted if distance exceeds 0.2" (5 mm). See RING GEAR BACK-LASH
procedure under DIFFERENTIAL ASSEMBLY (LIMITED SLIP) under OVERHAUL.
LIMITED SLIP DIFFERENTIAL PRELOAD
1) Place transmission in Neutral. Block front wheels. Raise
one rear wheel off ground and remove wheel. Release parking brake.
2) Using torque wrench and axle puller adapter, measure
starting torque while rotating wheel in forward direction. See Fig. 1.
Differential must be repaired if torque is less than 18 ft. lbs. (25
N.m).

INTRODUCTION TO MOTORIST ASSURANCE PROGRAM (MAP)
OVERVIEW OF MOTORIST ASSURANCE PROGRAM
The Motorist Assurance Program is the consumer outreach
effort of the Automotive Maintenance and Repair Association, Inc.
(AMRA). Participation in the Motorist Assurance Program is drawn from
retailers, suppliers, independent repair facilities, vehicle
manufacturers and industry associations.
Our organization's mission is to strengthen the relationship
between the consumer and the auto repair industry. We produce
materials that give motorists the information and encouragement to
take greater responsibility for their vehicles-through proper,
manufacturer-recommended, maintenance. We encourage participating
service and repair shops (including franchisees and dealers) to adopt
(1) a Pledge of Assurance to their Customers and (2) the Motorist
Assurance Program Standards of Service. All participating service
providers have agreed to subscribe to this Pledge and to adhere to the
promulgated Standards of Service demonstrating to their customers that
they are serious about customer satisfaction.
These Standards of Service require that an inspection of the
vehicle's (problem) system be made and the results communicated to the\
customer according to industry standards. Given that the industry did
not have such standards, the Motorist Assurance Program successfully
promulgated industry inspection communication standards in 1994-95 for
the following systems: Exhaust, Brakes, ABS, Steering and Suspension,
Engine Maintenance and Performance, HVAC, and Electrical Systems.
Further, revisions to all of these inspection were recently published.
Further, revisions to all of these inspection communication standards
are continually republished. In addition to these, standards for Drive
Train and Transmissions have recently been promulgated. Participating
shops utilize these Uniform Inspection & Communication Standards as
part of the inspection process and for communicating their findings to
their customers.
The Motorist Assurance Program continues to work
cooperatively and proactively with government agencies and consumer
groups toward solutions that both benefit the customer and are
mutually acceptable to both regulators and industry. We maintain the
belief that industry must retain control over how we conduct our
business, and we must be viewed as part of the solution and not part
of the problem. Meetings with state and other government officials
(and their representatives), concerned with auto repair and/or
consumer protection, are conducted. Feedback from these sessions is
brought back to the association, and the program adjusted as needed.
To assure auto repair customers recourse if they were not
satisfied with a repair transaction, the Motorist Assurance Program
offers mediation and arbitration through MAP/BBB-CARE and other non-
profit organizations. MAP conducted pilot programs in twelve states
before announcing the program nationally in October, 1998. During the
pilots, participating repair shops demonstrated their adherence to the
Pledge and Standards and agreed to follow the UICS in communicating
the results of their inspection to their customers. To put some
"teeth" in the program, an accreditation requirement for shops was
initiated. The requirements are stringent, and a self-policing method

NOTE: Whenever transmission or drivetrain service is performed
that affects the suspension alignment, for example,
removing the engine cradle, it is required that the
alignment be checked and corrected if necessary.
