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
3. Reconnect EGR volume control valve harness connector.
4. Remove EGR volume control valve from cylinder head.
(The EGR volume control valve harness connector should remain connected.)
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.
