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:

• The EEGR valve wiring is open.

• EEGR Pin #1: Power(Main Relay)

• EEGR Pin #5: ECU Pin #A48

- Actions

• Check EEGR valve wiring.
