id0140f2807600

Note
•  Perform the following test only when directed.

Voltage Inspection

1.  Switch the ignition to ON.

2.  Monitor the EGRP PID using the M-MDS.

EGRP PID
0.8—1.0 V

3.  Start the engine and warm up the engine completely.

4.  Command the EGRP PID from 0 to 100 % using simulation function.

5.  Verify that the EGRP PID reading change according to EGRP commanded value.

―  If not as specified, replace the EGR valve. (See EGR VALVE REMOVAL/INSTALLATION [MZR-CD 2.2].)
