EXHAUST GAS RECIRCULATION (EGR) SYSTEM

GENERAL INFORMATION

The electronically-controlled EGR system consists of an EGR valve, engine-ECU and various sensors.
The EGR valve is optimally controlled by the engine-ECU in response to the engine operation conditions,
based on data input from each of the sensors. In this way, the EGR valve is controlled to reduce NOx
emissions while maintaining good engine performance.

OPERATION

The EGR valve is being closed and does not recirculate exhaust gases under one of the following conditions.
Otherwise, the EGR valve is opened and recirculates exhaust gases.



The engine coolant temperature is low.



The throttle valve is widely opened.

EGR VALVE CHECK

1.

Disconnect the EGR valve connector.

2.

Measure the resistance between the EGR valve side
connector terminal 4 and terminal 6.

Standard value: 7.5 – 8.5 

Ω

 (at 20



C)

3.

If the resistance is outside the standard value, replace
the EGR valve.

EGR VALVE POSITION SENSOR CHECK

1.

Disconnect the EGR valve connector.

2.

Measure the resistance between the EGR valve side
connector terminal 2 and terminal 3.

Standard value: 2.4 – 5.6 

Ω

 (at 20



C)

3.

If the resistance is outside the standard value, replace

GENERAL

OUTLINE OF CHANGES



The service procedures for the clutch pedal have been changed due to the addition of the clutch
switch to control the engine <4G93, F9Q1>.



The clutch control have been changed due to the adoption of the F5MV1 transmission <F9Q1>.

ON-VEHICLE SERVICE

CLUTCH PEDAL INSPECTION AND
ADJUSTMENT <4G93, F9Q1>

1.

Turn up carpet, etc. under the clutch pedal.

2.

Measure the clutch pedal height.
Standard value (A):

173.3 – 176.3 mm <L.H. drive vehicles – 4G93>

171.7 – 174.7 mm <L.H. drive vehicles – F9Q1>

172.8 – 175.8 mm <R.H. drive vehicles>

3.

If the height of the clutch pedal is outside the standard
value, loosen the lock nut and adjust the pedal height to the
standard value using the push rod.

4.

Check the marked area for secure contact after adjustment.

5.

Measure the play at the clutch pedal clevis pin.

Standard value (B): 1 – 3 mm

6.

If the clutch pedal pin play is not within the standard value,
loosen the locking nut and move the push rod to adjust.

Caution
Do not push in the master cylinder push rod at this
time.

7.

Turn back the carpet, etc.

BLEEDING <F9Q1>

Specified brake fluid: DOT 3 or DOT 4

Caution
Avoid using a mixture of the specified fluid and other
fluid, otherwise the clutch fluid will deteriorate resulting
clutch fault.
