EGR VALVE CHECK <MPI>
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.
Vacuum
5.3 kPa or less
27 kPa or more
5. Replace the gasket, and tighten to the specified torque.
Specified torque: 22 Nm
EGR CONTROL SOLENOID VALVE CHECK
<MPI>
NOTE
When disconnecting the vacuum hose, always make a mark
so that it can be reconnected at original position.
1. Disconnect the vacuum hose (yellow stripe, green stripe)
from the solenoid valve.
2. Disconnect the harness connector.
3. Connect a hand vacuum pump to the nipple to which
the green-striped vacuum hose was connected.
4. Check airtightness by applying a vacuum with voltage
applied directly from the battery to the EGR control solenoid
valve and without applying voltage.
Battery voltage
Not applied
Applied
5. Measure the resistance between the terminals of the
solenoid valve.
Standard value: 28 – 36 Ω (at 20 C)
