(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). |
