Note
Do not remove the electric vacuum regulating valve.
INSPECT ELECTRIC VACUUM REGULATING VALVE
Measure the resistance of the electric vacuum regulating valve (E-VRV).
| Standard resistance | ||||||
|---|---|---|---|---|---|---|
|
If the result is not as specified, replace the electric EGR control valve assembly with E-VRV.
Check operation of the E-VRV.
When a vacuum of 66.7 kPa (500mmHg, 19.7 in.Hg) is applied to the port E, check that air flows from port F to the filter.
If the result is not as specified, replace the electric EGR control valve assembly with E-VRV.
Apply battery voltage across terminals 1 and 2.
Check that air flows from port F to port E.
If the result is not as specified, replace the electric EGR control valve assembly with E-VRV.
