Hyundai Tucson: Electric Exhaust Gas Re-circulation (EEGR) Control Valve
Hyundai Tucson - Fourth generation (NX4) - (2020-2023) - Workshop Manual / Engine Control - Fuel System / Electric Exhaust Gas Re-circulation (EEGR) Control Valve
Description
The Electric EGR Control Valve is installed in between the EGR cooler and the exhaust line and is a solenoid valve. This valve controls EGR (Exhaust Gas Recirculation) amount by the ECM's duty control signal depending on engine load and the need of intake air.
The Exhaust Gas Recirculation (EGR) system is used to add the exhaust gas to intake air in order to reduce an excess of air and the temperature in the combustion chamber.

Inspection
Motor
- Turn the ignition switch OFF.
- Disconnect the EEGR valve connector.
- Check that the EEGR valve is stuck by foreign material.
- Measure resistance between motor 4 and 5 control terminals of the motor.
- Check that the resistance is within the specification
Feedback Position Sensor
- Connect the diagnostic tool to the data link connector.
- Perform the fully open and the fully closing operation of the EEGR valve by using the actuation test.
- Check that the voltage is within the specification.
Removal
- Turn the ignition switcg OFF, and disconnect the batteiy negative (-) terminal.
- Remove the EGR cooler.
(Refer to Engine Mechanical System - "EGR Cooler")
- Remove the EEGR control valve after loosening the mounting bolt (A).
Tightening Torque : 18.6 - 23.5 N.m (1.9 - 2.4 kgf.m, 13.7 - 17.3 lb-ft)
Installation
WARNING
- Install the component with the specified torques.
- Note that internal damage may occur when the component is dropped. In this case, use it after inspecting.
- Use care to keep foreign material out of the component.
- Install in the reverse order of removal.
