INSPECTION PROCEDURE 1. INSPECT VACUUM SWITCHING VALVE (for Active Control Engine Mount System)
(a) Measure the resistance.
| (1) Measure the resistance according to the value(s) in the table below.
Standard Resistance: |
Tester Connection | Condition |
Specified Condition | |
1 - 2 |
20°C (68°F) | 37 to 44 Ω | |
1 - Body ground | 10 kΩ or higher | |
2 - Body ground | 10 kΩ or higher |
If the result is not as specified, replace the vacuum switching valve (for active control engine mount system). |

(Vacuum Switching Valve (for Active Control Engine Mount System)) | | |
(b) Check the operation of the vacuum switching valve (for active control engine mount system).
| (1) Using a vacuum pump, apply a vacuum of 67 kPa (503 mmHg, 19.8 in. Hg) to port (F) and check that the vacuum is maintained.
OK: Vacuum pressure holds. If the result is not as specified, replace the vacuum switching valve (for active control engine mount system). |
|
| (2) Check that air flows from port (E) to port (G). Standard:
Air flows from port (E) to port (G). If the result is not as specified, replace the vacuum switching valve (for active control engine mount system). |
 |
|
*a | Port (E) | |
*b | Port (G) | |
*c | Air | | |
| (3) Apply battery voltage to the terminals and check that air flows from port (E) to port (F).
Standard: Air flows from port (E) to port (F). If the result is not as specified, replace the vacuum switching valve (for active control engine mount system). |
 |
|
*a | Port (E) | |
*b | Port (F) | |
*c | Air | | | |
