ENGINE AND EMISSION CONTROL SYSTEM 6E1-15
ON-VEHICLE SERVICE
ACCELERATOR CABLE ADJUSTMENT
With accelerator pedal depressed fully (1), check clearance
between throttle lever (2) and lever stopper (3) (throttle body)
which should be within following specification.
If measured value is out of specification, adjust it to specification
with cable adjusting nut (4).
Accelerator cable adjustment clearance (with pedal
depressed fully)
“a” : 0.5 – 2.0 mm (0.02 – 0.07 in.)
IDLE SPEED/IDLE AIR CONTROL (IAC) DUTY
INSPECTION
Before idle speed/IAC duty check, make sure of the following.
Lead wires and hoses of Electronic Fuel Injection and engine
emission control systems are connected securely.
Accelerator cable has some play, that is, it is not tight.
Valve lash is checked and adjusted according to mainte-
nance schedule.
Ignition timing is within specification.
All accessories (wipers, heater, lights, A/C, etc.) are out of
service.
Air cleaner has been properly installed and is in good condi-
tion.
No abnormal air inhaling from air intake system.
After above items are all confirmed, check idle speed and IAC
duty as follows.
NOTE:
Before starting engine, place transmission gear shift
lever in “Neutral” (shift selector lever to “P” range for A/T
vehicle), and set parking brake and block drive wheels.

6E1-16 ENGINE AND EMISSION CONTROL SYSTEM
1) Connect SUZUKI scan tool (1) to DLC with ignition switch
OFF, if it is available.
2) Warm up engine to normal operating temperature.
3) Check engine idle speed and “IAC duty” as follows :
4) When using SUZUKI scan tool :
a) Select “Data List” mode on scan tool to check “IAC duty”.
(A) : 09931-76011 (SUZUKI scan tool)
(B) : Mass storage cartridge
(C) : 09931-76030 (16/14 pin DLC cable)
5) When using duty meter (vehicle without immobilizer indicator
lamp) :
a) Set tachometer.
b) Using service wire (2), ground “Diag. switch terminal” (4) in
monitor connector (3) and connect duty meter between
“Duty output terminal” (5) and “Ground terminal” (6) of mon-
itor connector (3).
6) If duty and/or idle speed is out of specifications, inspect idle
air control system referring to Diagnostic Flow Table B-4 Idle
Air Control System Check in Section 6.
Engine idle speed and IAC duty
7) Remove service wire from monitor connector (1).
8) Check that specified engine idle speed is obtained with A/C
ON if vehicle is equipped with A/C.
If not, check A/C ON signal circuit and idle air control sys-
tem.
[A] : When using SUZUKI scan tool
[B] : When using duty meter (Vehicle without immobilizer indicator lamp)
NOTE:
IAC duty can be checked using monitor connector only
for vehicle not equipped with immobilizer indicator lamp.

ENGINE AND EMISSION CONTROL SYSTEM 6E1-17
IDLE MIXTURE INSPECTION / ADJUSTMENT (VEHI-
CLE WITHOUT HEATED OXYGEN SENSOR)
All vehicles not equipped with heated oxygen sensor are shipped
with their CO % factory adjusted as follows.
Engine idle mixture (CO %)
0.5 – 1.5 % at specified idle speed
Idle mixture adjustment should never be changed from the origi-
nal factory setting. However, if during diagnosis, the check indi-
cates idle mixture to be the cause of a driver performance
complaint or emission failure, the idle mixture can be adjusted
using the following procedures.
1) Check idle speed according to “Idle Speed Inspection” sec-
tion.
2) Using exhaust gas tester, check that idle mixture CO % is
within above specification. If it is out of specification, adjust it
to specification by turning resistor knob.
3) If idle mixture has been adjusted, confirm that idle speed is
within specification. NOTE:
For this inspection and adjustment, exhaust gas tester
(CO meter) and engine tachometer are necessary.
NOTE:
Turning CO adjusting resistor knob to “A” increases CO
% (A/F mixture becomes rich) and turning it to “B”
decreases CO % (A/F mixture becomes lean).
1. CO adjusting resistor

THROTTLE BODY
ON-VEHICLE INSPECTION
Check that throttle valve lever (1) moves smoothly.
REMOVAL
1) Disconnect negative cable at battery.
2) Drain cooling system.
3) Disconnect accelerator cable (1) from throttle valve lever.
4) Disconnect IAT sensor connector and remove air cleaner
assembly with air cleaner outlet hose.
1. Throttle body 4. Gasket 7. TP sensor screws
2. Throttle stop screw 5. Idle air control valve Tightening torque
3. TP sensor 6. IAC valve screws Do not reuse.

ENGINE AND EMISSION CONTROL SYSTEM 6E1-19
5) Disconnect electric connector from TP sensor (1) and IAC
valve (2).
6) Remove throttle body from intake manifold.
7) Disconnect engine coolant hoses from throttle body.
DISASSEMBLY
Remove TP sensor and IAC valve from throttle body.
CLEANING
Clean throttle body bore (1) and idle air passage (2) by blowing
compressed air.
REASSEMBLY
1) Install IAC valve to throttle body referring to “IAC valve Instal-
lation” section.
2) Install TP sensor to throttle body referring to “TP sensor
Installation” section.
INSTALLATION
1) Clean mating surfaces and install throttle body gasket to
intake manifold.
Use new gasket.
2) Connect engine coolant hoses.
NOTE:
While disassembling and assembling throttle body, use
special care not to deform levers on throttle valve shaft
or cause damage to any other parts.
NOTE:
TP sensor, idle air control valve or other components
containing rubber must not be placed in a solvent or
cleaner bath. A chemical reaction will cause these parts
to swell, harden or get distorted.
