What happens when the EGR control solenoid is activated?
When the EGR control solenoid is activated, a passage is opened up that allows exhaust gases into the intake manifold. The EGR solenoid is controlled by the engine computer, and activated at very specific times in order to achieve the best performance, efficiency, and emissions from the engine.
How is the EGR system controlled by the computer?
The EGR system is controlled by the EGR control solenoid. When the EGR control solenoid is activated, a passage is opened up that allows exhaust gases into the intake manifold. The EGR solenoid is controlled by the engine computer, and activated at very specific times in order to achieve…
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.
What is the average rating of the EGR system?
Average rating from 129,829 customers who received a Exhaust and Emission System Inspection. The exhaust gas recirculation system, also known as the EGR system, is an emission system that is found on many road going cars and trucks.
What does the solenoid do on an EGR battery?
The solenoid controls a rapid-deployment valve to regulate the flow of vacuum, through the ports, to the EGR valve. 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.
When to test the Ford EGR valve solenoid?
The following are the most common symptoms that a Ford (or Mercury or Lincoln) car or truck will usually experience when there’s a fault in the EGR System: Car or truck runs fine, but the check engine light (CEL) is on with an EGR Valve Fault Code: P0401 EGR System Flow Insufficient. P01406 EGR Valve Pintle Position.
