EGR Valve Inspection

(1) Remove the EGR valve and check if for sticking, deposit
of carbon, etc_

If such condition exists , clean with adequate solvent to
ensure tight valve seat contact.

2)Connect a hand vacuum pump to the EGR valve.
Apply a vacuum of 67 kPa and check air tightness
Blow in air from one passage of the EGR to check
condition as follows:

Disconnect the vacuum hose (yellow stripe, green stripe)
from the solenoid valve.

2Disconnect the harness connector:

3Connect a hand vacuum pump to the nipple to which the
