DIESEL CONTROL SYSTEM
Specification : When Electric EGR control valve does not operate 6% duty) at idle : 340mg/st ± 50 mg/st
Fig.1) Check if "AIR MASS PERCYLINDER"l is 340mg/st
50mg/st without EEGR operation at warm idle
(Electric EGR control valve 6% duty)
Electric EGR control valae operates as decelerating after rapid acceleration when idle EEGR does not operate, Electric
EGR control valve operating duty decreases as time goes by. This controlling process lasts for about 3 min. and Electric
TERMINAL AND CONNECTOR INSPECTION
Refer to DTC P0489.
POWER CIRCUIT INSPECTION
Check power circuit voltage
IG KEY "OFF", ENGINE "OFF".
Disconnect Electric EGR control valve connector
IG KEY "ON"
Measure the voltage of terminal 2 of Electric EGR control valve connector
Specification : 11.5V~13.0V
Is the measured voltage within the specification?
▶ Go to "Control Circuit Inspection".
▶ Repair E/R FUSE ＆ RELAY BOX 15A INJ fuse and related circuit and go to "Verification of Vehicle Repair".
