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.
VacuumPassage of air
5.3 kPa or lessAir is not blown out
27 kPa or moreAir is blown out
5. Replace the gasket, and tighten to the specified torque.
Tightening torque: 20±2 N·m
EGR PORT VACUUM CHECK
1. Disconnect the vacuum hose (White stripe) from the
throttle body EGR vacuum nipple and connect a hand
vacuum pump to the nipple.
2. Start the engine and check vacuum remains fairly constant
after racing the engine.
