High EGR Close Position
Deviation

Low EGR Position Signal

- Causes

• The difference between E-EGR

position demand (MAP) value and
E-EGR position feedback signal
value is over 15% (the sensor
output indicates EEGR is closed
over 15% in the open status).

- Actions

• Measure the resistance of E-EGR

valve sensor.

• Check the sensor and actuator

wiring harness.

• Check the unit.

- Diagnosis of E-EGR signal for the

followings:

• Sensor signal is high or low.

• Total resistance value: 4

Ω +/-40%

• Sensor output range: 1.2 ~ 4.0 V

• Total sensor resistance: 4 k

Ω ± 40%

• Total motor resistance: 8.0

Ω ± 0.5Ω

- Check pin for the followings:

• Check sensor reference voltage

(5V) - ECU Pin #A33

• Sensor signal - ECU Pin #A82

• Sensor GND - ECU Pin #A09

- Actions

• Measure the resistance of E-EGR

valve sensor.

• Check the sensor and actuator

wiring harness.

• Check the unit.

High EGR Open Position
Deviation

- Causes

• The difference between E-EGR

position demand (MAP) value and
E-EGR position feedback signal
value is over 15% (the sensor
output indicates E-EGR is open
over 15% in the close status).

- Actions

• Measure the resistance of E-EGR

valve sensor.

• Check the sensor and actuator

wiring harness.

• Check the unit.
