Can you accumulate carbon in an EGR valve?
Carbon can’t accumulate in an EGR valve in a short time, unless there is something horribly wrong with the engine, which you would know, because the car would be nearly impossible to drive. You need a new mechanic. I agree with mcparadise.
What to do if your EGR valve is stuck?
Remove and clean, or replace, the plugged up tube that FEEDS the EGR valve. If this is the same code as before it sounds like either a clogged EGR passage or a stuck EGR valve. The entire passage way needs to be checked out for clogs.
What causes a low flow code on an EGR valve?
Sometimes EGR valves are fed by an external tube coming from the exhaust manifold. These tubes can plug up and throw a “EGR low flow” code. Remove and clean, or replace, the plugged up tube that FEEDS the EGR valve. If this is the same code as before it sounds like either a clogged EGR passage or a stuck EGR valve.
When do you need an EGR system code?
Getting an EGR system code does not necessariy mean the EGR valve itself is bad. Once a code is obtained this is when the manual and the diagnostic procedure is used to determine exactly where the problem lies in the EGR system. as i said. CODE PLEASE!

What happens when you get an EGR system code?
Carbon buildup can occur at even a short interval and it sounds to me like the shop is guessing. Getting an EGR system code does not necessariy mean the EGR valve itself is bad.

What happens when you replace the EGR in a car?
When you replace the EGR, which may not have been necessary, you MUST clean out all the carbon from the passages. Carbon may have been clogging the passages, leading to the code to begin with, and the old EGR may have been good. is your car subject to emissions testing? If not, don’t worry about it…
When does the Check Engine light come on in a Honda?
This article applies to the Honda Civic (1992-2000), and Accord (1990-2002). The check engine light in your Honda offers important diagnostic information, which will alert you of a serious problem like a bad catalytic converter. However, the check engine light also appears when the fuel tank cap is loose, or a change in humidity has occurred.

How much does it cost to replace the EGR valve on a Honda Accord?
You will need; wire brush, some carb cleaner or brake cleaner, a shop vac, new EGR gasket $1-$2 and new EGR chamber gasket $32.00 from Honda. Remove the fuel rail with the injectors intact if possible. (Do it slow and gentle) Unbolt the EGR valve. Unbolt the EGR chamber underneath the fuel, that is bolted on to the intake manifold.
Are there any problems with the Honda EGR system?
But has anyone else experienced repeat problems with the EGR system within such a short timeframe? If this is the V6 Accord, it very well could be an issue with carbon buildup again. It seems there was a tech bulletin which was issued by Honda about it for the 98-01 Accord and 99-02 Odyssey.
Can a bad EGR valve cause poor acceleration?
Answer: The EGR could be stuck open. If the engine is fed exhaust fumes continuously, this can overheat the valve, cause poor acceleration. Check the EGR system and see if a bad vacuum solenoid is keeping the valve opened. Check the control circuit as well.
Where can I find the EGR valve on my car?
Or visit an auto parts retailer on the Web, and enter your vehicle information to look for the EGR valve. Many auto parts stores online keep a database of auto parts photos or images for many vehicle makes and models. You may find a picture of the EGR valve for your particular model.
How to test an EGR valve with a hand mirror?
As you do this, watch the valve diaphragm movement. Use a small hand mirror for this, if necessary. If the stem or diaphragm doesn’t move, disconnect the thin vacuum hose from the top of the valve. Place your finger on the opening of the vacuum hose you just disconnected. Increase engine rpm again as you did in the previous step.
What’s the best way to clean an EGR valve?
Cleaning the Valve: After removing the valve, use an EGR valve cleaner, if possible. However, you can use carburetor cleaner or solvent as well. Apply the cleaner to the passages at the bottom of the valve, intake and exhaust passages. Use a dull scraper and wire brush to remove carbon deposits from the bottom of the valve, plunger and valve seat.
