What is the function of the EGR valve?
It connects the exhaust manifold to the intake manifold and is controlled by either a vacuum or a built-in electric step motor. The function of the EGR valve is to control the flow of exhaust gas being recirculated depending on the engine load.
How do you find the EGR valve in an engine?
Remove the vacuum hoses from the valve and inspect the lines. Spray carburetor cleaner inside the lines. Clean out the lines using a pipe cleaner if needed. If there are bolts attaching the valve to the engine, remove them. If the mounting gasket is in good shape you can set it aside and reuse it.

Where is the EGR valve on a car?
The EGR Valve (Exhaust Gas Recirculation) valve is found on almost all modern engines and is considered part of the emissions package of your vehicle.
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.
Why does the EGR valve work at low throttle angles?
It is true that the EGR recycles exhaust gas through the engine and those gasses are less than optimum for combustion. However, at low throttle angles your engine isn’t struggling to make power so much as it is struggling to work against the vacuum being created by the pistons traveling up and down the bore.
Where is the exhaust gas recirculation valve located?
Exhaust gas recirculation. EGR valve the top of box on top of the inlet manifold of a Saab H engine in a 1987 Saab 90. In internal combustion engines, exhaust gas recirculation (EGR) is a nitrogen oxide (NOx) emissions reduction technique used in petrol/gasoline and diesel engines.
The EGR valve is the main component of the EGR system and it’s normally closed. It connects the exhaust manifold to the intake manifold and is controlled by either a vacuum or a built-in electric step motor. The function of the EGR valve is to control the flow of exhaust gas being recirculated depending on the engine load.
Where is the EGR valve on a GMC Envoy XL?

What are the functions of the EGR valve?
The function of the EGR valve is to recirculate small amounts of exhaust back into the combustion chambers of the engine in order to decrease the combustion temperature, thereby reducing the formation of smog-producing nitrogen oxides. EGR valves can malfunction by becoming stuck open or closed due to carbon buildup.
How much does an EGR valve cost?
Having the EGR valve replaced on your car should cost between $147 to $548 , which will cover the cost of parts an labor. You can pick up the valve itself for anywhere between $70 and $490, depending on the type of car you own and what part you buy. EGR Valve Cost Comparison
Where does the vacuum line from the EGR valve go?
Follow the vacuum line from the front of the vehicle where it connects to the EGR solenoid through the conduit that carries it to the EGR valve at the rear of the engine compartment. The easiest way is to track the uniquely colored vacuum line along the path between its two connection points. on the driver’s side.
Can you clean EGR valve?
To Clean A Mechanical EGR Valve. 1. Clean and inspect the vacuum hose. Remove the vacuum hose and inspect closely for wear (cracks or weak spots), then clean out the carbon deposits either with a spray can of carburetor cleaner or with a pipe cleaner if the deposits are hardened or compacted.
