Faulty EGR Close Position
EGR Valve Circuit Short
- Causes
• The EGR position is not closed
when EGR is not operated within
50 seconds with the engine idling.
- Check pin for the followings:
• EEGR #1: Valve power (Main relay)
• EEGR #2:
Sensor (Reference voltage) . . ECU #A33
• EEGR #4:
Sensor (Ground) . . ECU #A09
• EEGR #5:
Valve drive (PWM) . .. ECU #A48
• EEGR #6:
Sensor (Signal) . . .. ECU #A82
- Actions
• Check EEGR valve and sensor wiring.
• Visually check the unit and
replace if necessary.
• Refer to DTCs (P0407 and P0408).
- Check pin for the followings:
