DIESEL CONTROL SYSTEM FLA -279 Specification : When Electric EGR control valve does not operate 6% duty) at idle : 340mg/st ± 50 mg/st Fig.1 Fig.2 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 EGNG012R TERMINAL AND CONNECTOR INSPECTION E24B9677 Refer to DTC P0489. POWER CIRCUIT INSPECTION EF73F372 1. Check power circuit voltage 1) IG KEY "OFF", ENGINE "OFF". 2) Disconnect Electric EGR control valve connector 3) IG KEY "ON" 4) Measure the voltage of terminal 2 of Electric EGR control valve connector Specification : 11.5V~13.0V 5) Is the measured voltage within the specification? YES ▶ Go to "Control Circuit Inspection". NO ▶ Repair E/R FUSE & RELAY BOX 15A INJ fuse and related circuit and go to "Verification of Vehicle Repair". |
