EGR VALVE CHECK
1. Remove the EGR valve and inspect for sucking carbon deposits etc. If necessary 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 (20 in.Hg) of vacuum and check to be sure that the vacuum is maintained.
4. As described in the chart, apply a vacuum and check the passage of air by blowing through one side of the EGR passage.
NOTE: Passage of air should be checked by blowing into the valve pod.
5. Reinstall the EGR valve using a new gasket and tighten to the specified torque.
Tightening torque: 20 ± 2 N.m (14 ± 1.4 ft.lb)
