ELECTRONIC CONTROLLED ENGINE MOUNT
DescriptionINFOID:0000000003856835
The electronic controlled engine mount control solenoid valve controls the intake manifold vacuum signal for
electronic controlled engine mount. The electronic controlled engine mount control solenoid valve is moved by
ON/OFF signal from the ECM. When the solenoid is OFF, the vacuum signal from the intake manifold is cut.
When the solenoid is ON, the intake manifold vacuum signal is sent to the electronic controlled engine mount.
