How does a solenoid work on an EGR valve?
Blow through the vacuum hose. Air should pass through when it is energized. This test determines whether the valve is opening when it is energized, allowing unrestricted flow of vacuum. If the solenoid fails any of these tests, replace it. Some solenoids were designed to modulate the vacuum to the EGR valve.
What kind of fuse to use on EGR solenoid?
Make a jumper wire with an in-line fuse holder and install a 10-amp fuse. Crimp each end of the fuse holder to a section of wire using crimp connectors. Make another jumper wire and attach both wires to the connectors on the solenoid.
What should I do if my solenoid is not working?
Blow forcefully through one of the hoses. Air should not pass through. If air cannot pass through, neither can vacuum and the valve is closing properly. Attach the loose jumper wire back on the battery. The solenoid should click again. Blow through the vacuum hose. Air should pass through when it is energized.
When to use an EGR solenoid on an engine?
EGR solenoids are used to switch engine vacuum on and off at the right time. The time is based strictly on engine load and temperature. 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.
What happens if you don’t have an EGR system?
Without it the EGR system will not be able to recirculate the exhaust gases properly, which can lead to issues with engine performance and even emissions.
When does the Check Engine light come on on an EGR?
Check Engine Light comes on. An illuminated Check Engine Light is another symptom of a bad or failing EGR control solenoid. If the computer detects an issue with the EGR solenoid, circuit, or system, it will set off the Check Engine Light to notify the driver of the issue.
Is the Check Engine Light a sign of a bad solenoid?
An illuminated Check Engine Light is another symptom of a bad or failing EGR control solenoid. If the computer detects an issue with the EGR solenoid, circuit, or system, it will set off the Check Engine Light to notify the driver of the issue.
