>> GO TO 4.

NO

>> Repair or replace error-detected parts.

4.

CHECK EGR VOLUME CONTROL VALVE

Check the EGR volume control valve. Refer to 

EC-961, "Component Inspection (EGR Volume Control Valve)"

.

Is the inspection result normal?

YES

>> Check intermittent incident. Refer to 

GI-45, "Intermittent Incident"

.

NO

>> Replace EGR volume control valve. Refer to 

EC-600, "ENGINE CONTROL SYSTEM :

.

Component Inspection (EGR Volume Control Valve)

INFOID:0000000012198487

1.

CHECK EGR VOLUME CONTROL VALVE-1

With CONSULT

1. Turn ignition switch ON and engine stopped.

2. On the CONSULT screen, select “ENGINE” >> “ACTIVE TEST” >> “EGR CONTROL VALVE”.

3. Operate “Up” or “Down”, set “EGR VALVE POSITION” to 0 deg, and check value “V1” of “EGR VALVE

POSITION SEN”.

Does “V1” become 1.2

±0.15 V?

YES

>> GO TO 2.

NO

>> Replace EGR volume control valve. Refer to 

EC-600, "ENGINE CONTROL SYSTEM :

Component Parts Location"

.

2.

CHECK EGR VOLUME CONTROL VALVE-2

With CONSULT

1. Operate “Up” or “Down”, set “EGR VALVE POSITION” to 70 deg, and check value “V2” of “EGR VALVE

POSITION SEN”.

Does “V2” become 4.0

±0.15 V?

YES

>> GO TO 3.

NO

>> Replace EGR volume control valve. Refer to 

EC-600, "ENGINE CONTROL SYSTEM :

Component Parts Location"

.

3.

CHECK EGR VOLUME CONTROL VALVE VISUALLY

1. Turn ignition switch OFF.

2. Check if any foreign objects interferes with EGR volume control valve.

EGR SENSOR C
(EGR sensor C circuit range/
performance)

ECM detects the following status continuously 
for 0.5 seconds or more:
A voltage signal transmitted from the EGR vol-
ume control valve position sensor is between 
0.32 V and 1.08 V under the following condi-
tions:
• After the ignition switch is turned OFF and 

the engine is stopped by “Self Shut-OFF”.
This diagnosis works only when the ignition 
switch is turned OFF and the engine is 
stopped by “Self Shut-OFF”.

• Engine coolant temperature: 65

°C (149°F) 

or more

• Intake air temperature: 5

°C (41°F) or more

• EGR volume control valve is stuck
