What does the EGR vacuum solenoid do?
The exhaust gas recirculation (EGR) solenoid is an electronic vacuum valve that distributes engine vacuum to the EGR valve when the computer commands it.
Where is EGR vacuum solenoid located?
It is normally attached to the engine block with a nut and is close to the EGR valve. The solenoid can be located by following the rubber vacuum hose from the EGR valve on the back of the engine block to the solenoid.
What happens if your EGR valve is blocked?
A faulty EGR valve can cause problems with the flow and operation of the EGR system leading to performance issues including a reduction in power, reduced acceleration and decreased fuel efficiency. It can also cause vehicle emissions to increase.
What happens if the EGR solenoid goes bad?
If the EGR solenoid fails it can disable the EGR system from recirculating exhaust gases. For certain engines this can cause a large increase in cylinder and exhaust gas temperatures. Excessively high cylinder temperatures can cause engine ping and knock, which can lead to serious engine damage if left unattended.
Where are the vacuum ports on an EGR solenoid?
The solenoid should click as it is powered by the battery. Remove one of the jumper wires from the battery and install vacuum hoses on the two vacuum ports located on the EGR solenoid. The solenoid controls a rapid-deployment valve to regulate the flow of vacuum, through the ports, to the EGR valve.
What happens if the EGR solenoid is not activated?
If the EGR circuit activates too soon, the engine will miss and run badly, or not at all. If it is defective and does not switch on at all, the engine will ping and rattle under a load or going uphill. It’s important that the EGR solenoid be in proper working order.
Are there any vacuum solenoids left in stock?

What is the EGR system on a Camry?
The EGR system on a vehicle is responsible for recirculating exhaust gasses in order to lower the vehicles emissions output. There are three main parts of the Camry’s EGR system. They are the EGR Valve, Differential Pressure Sensor, and the Actuator Solenoid.
