Engine Mount Vacuum Hose Check

  1. Disconnect upper vacuum hose from engine mount control solenoid valve. Install a hand-held vacuum pump to upper vacuum hose. Apply 20 in. Hg. Vacuum should hold. If vacuum holds, go to next step. If vacuum does not hold, check vacuum hose for leaks. If vacuum hose is okay, go to next step.
  2. Release and apply vacuum. Repeat a few times. If sensed idle vibration does not change with or without vacuum applied, replace affected engine mount. If sensed idle vibration changes noticeably with or without vacuum, test engine mount control solenoid valve. See CONTROL SOLENOID CIRCUIT CHECK .
