SERVICE ADJUSTMENT PROCEDURES
<2.0L DOHC Engine>
CURB IDLE SPEED INSPECTION
Caution
N14FHADThe improper setting (throttle valve opening) will increase
exhaust gas temperature at deceleration, reducing
catalys-tic converter life greatly and deteriorating exhaust gas
cleaning performance. It also has effect on fuel ‘consump-
tion and engine braking.
Pre-conditions for inspection
l Engine coolant temperature:
85-95°C (185-205°F)
l Lights, electric cooling fan and accessories: OFF
lTransaxle: Neutral (P for vehicles with automatic transaxle)l Steering wheel: Neutral position (vehicles with a power-
steering)l Check ignition timing and adjust if necessary. Refer to
GROUP 8.
NOTEWith vehicles for Canada, the headlights and taillights, etc.
remain on even when the lighting switch is turned OFF, but thiscauses no problems during inspection.
(1) Connect the tachometer to the engine speed detection
terminal.
(2)Run the engine for more than 5 seconds at an engine speedof 2,000 to 3,000 rpm.
(3) Run the engine at idle for 2 minutes.
(4) Read the idling rpm. If it is not within the specified speed,
check the idle speed control system.
Curb idle speed:
750f 100 rpm
NOTE1. Adjustment of the idling speed is usually unnecessary,
because this system controls the idling speed.
2.For rpm, one-half of the actual engine rpm is indicated,so the actual engine rpm is two times the indicated
value shown by the tachometer.

INJECTORSN14QTAGCHECKING OPERATION SOUND
Using a sound-scope, check the operation sound (“chi-chi-chi”)of injectors during idling or during cranking.
Check that as the rotating speed increases, the frequency of
the operating sound also increases.
Caution
Note that even if the injector you are checking is not
operating, you will hear the operating sound of the other
injectors.
NOTEIf no operating sound is heard from the injector that is being
checked, check the injector drive circuit. If there is nothing
wrong with the circuit, a defective injector or engine control
unit is suspected.
MEASURING RESISTANCE BETWEEN TERMINALS
(1) Remove the injector connector.
(2) Measure the resistance between the terminals.
Standard value: 13
- 16 L(Z [at 20°C (68”F)I(3) Install the injector connector.
IDLE SPEED CONTROL SERVO
INSPECTION
NlQQUAAb(1) Disconnect the idle speed control servo connector.

INJECTORS
NWXAHCHECKING OPERATION SOUND
Using a sound-scope, check the operation sound (“chi-chi-chi”)of the injectors during idling or during cranking.
Check to be sure that the operation sound increases when the
engine speed is increased.
Caution
Note that the sounds of other injectors may be heard even
though the injector being checked is not operating, so caremust be taken when checking.
NOTEIf the operation sounds cannot be heard, check the injector
activation circuit.
If this circuit is normal, there is probably a malfunction of the
injector or of the engine control unit.
MEASURING OF RESISTANCE BETWEEN TERMINALS
(1) Disconnect the connector for the injectors.
(2) Measure the resistance between terminals.
Standard value:
13
-16 S2 [at 20°C (68”F)]2
- 3 52 [at 20% (68”F)]
(3) Connect the connector for the injectors.
IDLE SPEED CONTROL SERVO
N14QUADCHECKING OPERATING SOUND
(1) Check that when the ignition switch is placed in the ON
position (the engine not started), the operating sound of thestepper motor can be heard over the idle speed control
servo.
(2) If no operating sound can be heard, check the stepper
motor drive circuit.
(If the circuit is good, a defective stepper motor or engine
control unit is suspected.)
