Where is the EGR located on a 2009 Dodge Avenger?
where is the EGR located on a 2009 dodge avenger 2.4L? The 2009 Dodge Avenger EGR valve is not shaped like the old EGR valve; it is a cylinder shape on this vehicle. It is located on the left side of the engine near the front. Where is the E.G.R. valve located on a 2011 Mazda MX5?
Where does the EGR valve in an engine come from?
So NOx in the atmosphere is not good. That’s where the EGR valve comes into play. It is designed to reduce the amount of NOx emissions from automobiles. This is accomplished by recirculating a portion of the exhaust. Engines have a small passage between the intake and exhaust manifold. The EGR regulates this passage.
Where is the EGR valve located on a 2005 ML350?
Where is the EGR valve located on a 2005 ml350? On the ml 350, the EGR valve, when looking at the engine from the front, will be on the right side, near the engine block, toward the front. Look for the telltale shape of the EGR valve. It may be in a sideways position.

When was the last Mercedes Benz E430 made?
Mercedes calls this series of E-Klasse the W210 chassis, and calls the E430 the E430W internally. This series of E-Klasse were available for model years 1997 – 2002. It was the last Mercedes introduced before Mercedes bought Chrysler in 1998.
What kind of engine does the Mercedes E430 have?
The E430 is the premium version of Mercedes popular E320 mid-sized sedan. The E430 has a V8 engine with sixteen (16) spark plugs and rear-wheel drive.
Where can I get free roadside service for my Mercedes E430?
Like all Mercedes, every E430 has eternal free roadside service. Just call (800) FOR-MERC anytime for help. The E430 visits Fletcher-Jones in Las Vegas, after a day at the track. (Race number and bugs are still on the windshield!)
How do you clean a mechanical 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.
What happens if you leave the EGR valve open?
Whether mechanical or electronic, EGR valves open and close to control the gas flow. If left open, the excess vacuum will cause the engine to act like it wants to stall, idling roughly or surging.
Where is the EGR valve on a 2006 Ford Mondeo?
Where is the EGR valve on a 2006 Ford Mondeo? Follow the air intake past the air filter, and it should go right into the engine. It should pass through a box right before it goes into the engine. That’s you’re throttle body. There should be a box or a can looking container attached off the side, right by that part of the air intake.
How does exhaust gas recirculation ( EGR ) work in an engine?
In internal combustion engines, exhaust gas recirculation (EGR) is a nitrogen oxide (NOx) emissions reduction technique used in petrol/gasoline and diesel engines. EGR works by recirculating a portion of an engine’s exhaust gas back to the engine cylinders.
What happens when the EGR valve fails to close?
When this flow pattern fails, you begin to notice a decline in engine performance. For instance, this will happen if the EGR valve fails to close completely as the engine idles, or fails to open when engine speed increases. Unfortunately, problems in the EGR system and valve will happen sooner or later.
How long does it take to test an EGR valve?
Today I’d like to throw some thoughts out on how to check a car’s EGR Valve and related EGR system components for proper operation. Most basic automotive systems can be pinpoint tested down to a faulty component in a matter of less than 20 minutes, regardless of the code.

How does the EGR system in a car work?
So what is an EGR system and how does it work? EGR stands for Exhaust Gas Recirculation, and as its name implies, this system allows exhaust gasses from your car to be re-circulated into the engine, helping to reduce emissions.
Do you need vacuum pump to test EGR valve?
Still, you can follow this guide along with the procedure described in your vehicle manual to test your EGR valve, if necessary. To apply one of the tests to the EGR valve, you’ll need a vacuum pump, which you can borrow-rent from a local auto parts store, if you don’t have one.
