Electric Egr Control Valve Inspection

Inspect the EGR valve.

1. When a vacuum of 26.7 kPa (200 mmHg, 7.87 in.Hg) is applied to the diaphragm chamber, check that the shaft rises and that air flows out.
   

2. Maintaining the above conditions, check that there are no leaks and that the shaft does not lower.
   

3. Check that the valve does not have heavy carbon deposits and is not stuck.
   If the result is not as specified, replace the electric EGR control valve assembly.
   

Inspect the electric vacuum regulating valve (for EGR).

1. Measure the resistance of the E-VRV.
   

   Standard resistance:

   Tester Connection	Specified Condition
   1 - 2	11 to 13 Ω at 20°C (68°F)
   1 - Body Ground 2 - Body Ground	10 MΩ or higher

   If the result is not as specified, replace the electric EGR control valve assembly.
   




2. Check that air flows from port E to the filter.
   If the result is not as specified, replace the electric EGR control valve assembly.
   

3. Apply battery voltage across terminals 1 and 2.
   

4. Check that air flows from port E to port F.
   If the result is not as specified, replace the electric EGR control valve assembly.
