1.Connect the M.U.T.-III to the diagnosis connector to check for date list item No.16.
2.Start the engine, and warm up the engine.
3.Raise the engine speed gradually, and make sure that the valve open degree changes
from 0% to 100%.

2.Connect the terminal (+) of the sensor power supply (5V) with the terminal No.3
of the EGR valve connector, and connect the terminal (-) of the sensor power supply (5V)
with the terminal No. 2.
3.A tester is to be connected between the terminal No.1 and No. 2.
4.Connect the terminal (+) of the power supply with the terminal No. 6 of the
EGR valve connector, and connect the terminal (-) of the power supply with the terminal
No. 4. Confirm the EGR valve is opened.
| note |
At this time, the power supply voltage is to be 5V. When the valve is not opened, increase the
voltage 1V by 1V. For each voltage, current is to be applied within 5 seconds. Once the valve
is opened, the voltage is not to be increased any more.

|
5.Confirm the voltage is changed between the terminal No. 1 and No. 2 together with the
EGR valve opening movement.
6.By the voltage changed, the DC is recognized as being normal
7.Use a new gasket and tighten the installation bolt to the tightening torque.
Tightening torque: 48 ± 6 N·m

1.Remove the EGR valve and check that the EGR valve is not stuck or clogged with carbon
deposits. Use a wire brush to clean the valve if necessary.
|
|
|
2.Using a new gasket, install the EGR valve by tightening its mounting bolts to the
specified torque.
Tightening torque: 48 ± 6 N·m
