id0140a1804500
1. Remove the differential pressure feedback EGR sensor with the connector still connected.
2. Install the vacuum pump to the narrower diameter of the differential pressure feedback EGR sensor.
3. Connect the M-MDS.
4. Turn the ignition switch to the ON position.
5. Using M-MDS, verify that the DPFEGR PID value is as indicated in the table.
