EGR VOLUME CONTROL VALVE
With CONSULT-II
1.
Disconnect EGR volume control valve harness connector.
2.
Check resistance between the following terminals.
●
terminal 2 and terminals 1, 3
●
terminal 5 and terminals 4, 6
If NG, replace EGR volume control valve.
If OK, go to next step.
3.
Remove EGR volume control valve from cylinder head.
4.
Reconnect EGR volume control valve harness connector.
5.
Turn ignition switch ON.
6.
Perform “EGR VOL CONT/V” in “ACTIVE TEST” mode with CONSULT-II. Check that EGR volume control
valve shaft moves smoothly forward and backward according to the valve opening.
If NG, replace the EGR volume control valve.
NOTE:
When installing the EGR volume control valve, make sure that the shaft is in the same position before
checking.
