Checking the technical condition
1. Turn off the ignition.
2. Disconnect the EGR control electric valve connector (EEGR).
3. Check for obstruction of the EEGR valve by foreign material.
4. Measure the resistance between (+) And (-) motor control outputs.
5. Check that the resistance is within specification.
6. Measure the resistance between the power and «masses» sensor.
7. Check that the resistance is within specification.
Withdrawal
1. Turn the ignition key to position «OFF» and disconnect the negative (-) battery wire.
2. Disconnect the connector (A) EEGR valve.
3. Turn away fixing bolts and remove the valve (IN) EEGR.
Installation
Attention.
- Tighten the component mounting bolts to the correct torque.
- Be careful not to drop the component. In the event of a drop, the component must be carefully checked before installation.
Installation is carried out in the reverse order of removal.
Note: Tightening torque: EEGR valve mounting bolt: 7.8 - 11.8 Nm.
Replacement
After replacing the electric EGR control valve (EEGR) you need to follow the procedure «Component Change Routine» (Component replacement program). Otherwise, a malfunction related to engine performance or exhaust control may occur and remain until the data on the new component is registered in the engine control unit.
1. Turn off the ignition.
2. Connect the diagnostic system scanner (GDS) to the diagnostic socket (DLC).
3. Turn on the ignition.
4. Select «Vehicle, Model year, Engine, System» (car, model year, engine, system).
5. Select «Vehicle S/W Management» (Vehicle software control).
6. Select «Component Change Routine» (Component replacement program).
7. Select «EGR Valve Change» (Exhaust Gas Recirculation Valve Replacement).
8. Follow the procedure as instructed on the screen.
