You don't. In my book they are items that if damaged or clogged they should be replaced. A new one will run you $8-$20 if you do the work your self.

Is the pipe bellow egr valve need to have carbon cleaned from those passages?
Yes, clean the cabor buildup from the EGR valve and that pipe.
If you have changed your egr valve and deleted the code and it still reads p0401 egr valve insuffasante flow what do you do now?
You also need to clean the "passages". EGR valve puts exhaust gas back into the engine intake under less than full power situations. When that happens exhaust deposits build up on the walls of the passages. Replacing the EGR valve was only half the repair, you also need to clean it out. There is a tube from under the EGR valve to the exhaust manifold. That is probably blocked.
How do you fix a code P0401 Suzuki 07?
Remove EGR valve and inspect for blocked or restricted passages.
Once the EGR valve is replaced is there anything else to do?
Typically the EGR valve is not the only problem.If you'll examine the exhaust gas passages when you have the EGR valve out of the engine, you'll notice that an older vehicle typically has quite a bit of built up deposits on the inside of the passages. These need to be cleaned at least sufficiently to allow the free flow of exhaust gas.Sometimes the cleaning process can be more time consuming than replacing the EGR valve.And SOMETIMES, you don't even need to replace the EGR valve; the problem can simply be the buildup of deposits.
How do you clean the EGR valve on a 2001 Honda Accord?
If you have less than 80,000 on it read below. Occasional problems on this vehicle are failures of the Exhaust Gas Recirculation (EGR) Valve Passages and the EGR valve (3.0L V6 engine only). Honda has extended the warranty on problems related to the EGR System to 8 years or 80,000 miles.
How do you replace the EGR valve in a 1996 Lexus ES300 to resolve 'insufficient flow' and 'check engine' message?
P0401 "egr insufficient flow" can indicate many things, including: 1-vacuum line plugged or leaking 2-pipe from exhaust to egr valve plugged 3-pipe to vacuum modulator valve from egr valve plugged 4-passages at egr are plugged 5-bad egr valve 6-bad EGR VACUUM MODULATOR VALVE I tried cleaning egr modulator valve, (beside/above egr)removed and tested egr vacuum & movement, inspected and cleaned all vacuum lines openings and pipes. All above did not work. I replaced the egr vacuum modulator valve. Light went out without a reset in about 30 miles of driving. Not sure if this valve can be cleaned. Retails for $69.US
Where is the egr valve located on an h22a4?
The EGR valve is located at the front of the h22a4 engine. The EGR valve is right beside of the front of the EGR valve.
Your 95 blazer service engine light is on and the code you got was p1406 manufacturer control auxiliary emission controlany one have a idea what this means and how to find problem?
Code 1406 is EGR Valve Pintle Position Circuit Error. As far as your EGR "pintle position" code is concerned. Your EGR valve is sticking or malfunctioning. Remove and CAREFULLY clean the EGR valve shaft and it's passages in the engine and reinstall with a NEW gasket. If this does not resolve the problem, replace the EGR valve.
How do you change the egr valve on a 96' dodge neon?
The EGR valve and electrical transducer should be replaced at the same time as they are matched. Remove EGR transducer from the air inlet duct. Disconnect vacuum supply tube from EGR transducer solenoid. Remove air inlet duct. Remove EGR tube to EGR valve screws. Remove EGR valve mounting screws. Remove EGR valve and transducer. Clean gasket surfaces. Discard old gaskets. If necessary, clean EGR passages. Loosely install EGR valve with new gaskets and finer tighten EGR tube fasteners. Tighten tube fasteners to 95 in lb, tighten EGR valve mounting screws to 200 in lb. Install air inlet duct. Connect vacuum supply tube to solenoid. Attach electrical connector to solenoid. Install EGR transducer onto air inlet duct.
What does it mean when the exhaust gas regulation light comes on?
If vacuum hose to EGR is ok, then valve may need to be replaced, or passages cleaned out.
Is there a difference between EGR valve and EGR sensor in a 2004 dodge ram?
A valve can be defined as a device that regulates flow, based on its ability to open, close, or obstruct passages or galleries. Therefore, the valve should be the mechanical moving device that actually permits the exhaust gasoline vapors to re-enter the combustion chamber, and that should leave the EGR sensor to be an electrical component that measures the concentration of exhaust gases, and relays the information to the ECM or PCM which then controls the EGR valve itself, and regulating the exhaust gas flow in that manner. Basically: * EGR valve is the mechanical component that physically regulates gases * EGR sensor measures concentration of gases, and instructs the EGR valve how much to regulate Hope this helps!
Can a bad EGR valve cause high hydrocarbons?
Yes, the EGR valve, or port EGR
