PERIODIC INSPECTION AND MAINTENANCE 2-63
OPERATION CHECK
1. Remove the EGR valve.
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.

CLEANING THE EGR VALVE
CAUTION
Do not use a solvent or detergent, which could
enter the motor and cause it to malfunction.
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.

EGR valve check
1. Remove the EGR valve and inspect for sticking,
carbon deposits, etc. If found, clean with a
suitable solvent so that the valve seats correctly.
2. Connect a hand vacuum pump to the EGR valve.
3. Apply 67 kPa of vacuum, and check that the
vacuum is maintained.
4. Apply a vacuum and check the passage of air by
blowing through one side of the EGR passage.
5. Replace the gasket, and tighten to the specified
torque.
