6.
Pre-inspection work
•
Check that the battery voltage is in the normal range.
7.
After-inspection work
•
Clear all past DTCs.
•
Check that no DTC is detected after test drive.
8.
Estimated failure factors
•
Damaged element inside EGR valve actuator
•
Soot adhesion to EGR valve sealing face and gas passageway, and motor abnormal heat rise due to damage
caused by hard foreign substances (Hardened carbon may peel off from EGR cooler upstream of EGR valve.)
*1. If there is no problem with the above, foreign substance damage occurred when the MIL was ON, but at present
the foreign substances are thought to have dropped off and normal operation restored.
*2. This DTC may be detected because there is freezing inside the EGR valve when the outside temperature is low.
When the interior thaws, however, normal operation will be restored.
