INSPECT VACUUM SWITCHING VALVE (for EGR Bypass Valve)
| *a | Component without harness connected (Vacuum Switching Valve) |
Inspect the No. 1 and No. 2 vacuum switching valves.
Measure the resistance according to the value(s) in the table below.
| Standard Resistance | |||||||||
|---|---|---|---|---|---|---|---|---|---|

If the result is not as specified, replace the vacuum switching valve.
| *1 | Port E |
| *2 | Port F |
| *3 | Vacuum |
| *4 | Air |
| *5 | Filter |
Check operation of the No. 1 and No. 2 vacuum switching valves.
When a vacuum of 67 kPa (500 mmHg, 19.7 in.Hg) is applied to port F, check that air flows from port E to the filter.
| *1 | Port E |
| *2 | Port F |
| *3 | Air |
Apply battery voltage across terminals 1 and 2.
Check that air flows from port E to port F.
If the result is not as specified, replace the vacuum switching valve.
