What is EGR vacuum solenoid?

What is EGR vacuum solenoid?

The exhaust gas recirculation (EGR) solenoid is an electronic vacuum valve that distributes engine vacuum to the EGR valve when the computer commands it.

What does a vacuum solenoid do in a car?

Vacuum operated EGR valves use a vacuum solenoid to vary the vacuum to the diaphragm and, in turn, open and close the EGR. Some valves also include a feedback sensor to inform the ECU of the valves position.

What is the vacuum solenoid for?

Vacuum valve solenoids are used to drive a vacuum valve and are offered in various DC or AC voltages. Solenoids for vacuum valves. Service or maintain a vacuum valve. Spare parts for limited downtime.

What does a vias solenoid do?

The VIAS control solenoid valve cuts the intake manifold vacuum signal for power valve control. The vacuum signal from the intake manifold is cut when the solenoid is off. When the PCM sends On signal, the coil pulls the plunger down, feeding the vacuum signal to the power valve actuator.

What is a power valve actuator?

Power-operated actuators, using gas pressure, hydraulic pressure or electricity, allow a valve to be adjusted remotely, or allow rapid operation of large valves. Power-operated valve actuators may be the final elements of an automatic control loop which automatically regulates some flow, level or other process.

CAN communication circuit U1000?
