Inspection |
1. |
Turn ignition switch OFF. |
2. |
Disconnect the EWGA connector. |
3. |
Check that the EWGA is stuck by foreign material. |
4. |
Measure resistance between motor (+) and (-) control terminals of the motor. |
5. |
Check that the resistance is within the specification.
|
1. |
Turn ignition switch ON. |
2. |
Connect the GDS to the data link connector(DLC). |
3. |
Check the output voltage at each position of the EWGA position sensor on current data item within the specification.
|
Removal |
1. |
Turn the ignition switch OFF and disconnect the battery negative (-) cable. |
2. |
Disconnect the EWGA connector (A). |
3. |
Remove the shaft link assembly (B) after removing the C-ring (A). |
4. |
Remove the EWGA after removing the bolts (A).
|
Installation |
1. |
Installation is the reverse order of removal.
|
Adjustment |
1. |
Check that the waste gate turbo charger is cool enough to work. |
2. |
Turn the ignition switch to OFF position. |
3. |
Connect the diagnostic tool to DLC connector (16 pin) under the driver side instrument panel. |
4. |
Turn the ignition switch ON position.
|
5. |
Select VIN or Vehicle on the initial screen. |
6. |
Enter "Engine Control" menu after slelecting vehicle
information (Vehicle model, Model year, Engine type) or entering the VIN
number. |
7. |
Access to GDS Engine > Current Data |
8. |
Without starting the engine, cycle the ignition ON for
5seconds then ignition OFF for 5seconds then check the "Adaption value
for the low mechanical stop of EWGA" on the GDS.
Repeat this step until the amount of the adaption value change compared to previous cycle is below 0.05V.
|
9. |
If the voltage value measured is not within the specified
voltage value, adjust the EWGA rod length. But, if no, no further
procedure is required.
|
10. |
Install the rod end part (C) to the turbo charger lever (D) temporarily. Don''t tighten the rod end lock nut (A). |
11. |
Turn the ignition switch ON/OFF 5 times. But hold 5 seconds at each IG ON or OFF state.
|
12. |
If the voltage value measured is not within the specified
voltage value, repeat 8~10 procedures untill the voltage value is within
the specified voltage value.
|
13. |
Check that " Adaption value for the lower mechancal stop of EWGA" is within the specified voltage value. |
14. |
If it is within the specified voltage value, install the turbo charger lever (D) and the rod end part (C).
|
15. |
Tighten the rod end locking nut (A). The turbo charger lever
(D) side and the rod end part (C) side should be parallel at this time. |
16. |
Install the C-ring (B). |
