Engine Mount Control System Check

  1. Ensure engine mount diaphragm actuator is working properly. To test actuator diaphragm, use a hand-held vacuum pump and apply about 9 in. Hg to actuator diaphragm. Actuator rod should move smoothly and diaphragm should hold vacuum. Replace as necessary. If engine mount is okay, go to next step.
  2. Warm engine to normal operating temperature. Ensure idle speed is about 800 RPM. Adjust idle speed as necessary. With engine at idle, depress brake pedal. Place transmission is gear.
  3. Have an assistant disconnect 6-pin engine mount control solenoid connector located near center of firewall. If sensed idle vibration changes noticeably, system is working properly. If sensed idle vibration does not change, check control solenoid circuit. See CONTROL SOLENOID CIRCUIT CHECK .
