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.
What is the code p4010 2001 jimmy?
I believe the code your getting is probably p0401 which is EGR system flow insufficient. Pull your EGR valve and clean the carbon off of it if it still gives that code you may have to pull the intake manifold and clean the EGR passages in it. I had that code in my wife's Buick and had to pull the intake because it was packed with carbon build up.
What could be the cause of a rough idle while in park on a 1994 Lincoln town car?
Remove the EGR valve and clean the passages and/or clean the MAF sensor in the air intake tube (use alcohol and be VERY carefull when cleaning the two small wires). Could also be the IAC or idle air control valve. There are very nice writeups on cleaning the IAC, MAF and EGR passages in the tech section at www.lincolnsonline.com
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 test the egr on a 1994 lesabre?
Testing an EGR value on a 1994 LeSabre is a complicated task. You need a multi-tester and wire piercing probes. The EGR must be tested with the unit still in place in the car and you must perform several different tests. For the average DIY'er it is a complex process. However, I can recommend a much simplier way. Carefully remove the two nuts that hold the EGR in place, being especially careful not to damage the EGR gasket. Once removed, inspect the smaller passage (on the bottom of the EGR). This passage should be closed (meaning, the spring loaded is all the way down or closed). If this passage on your EGR is open, I would replace the EGR. If the passage is closed, then I would would clean still clean both of the internal passages (the large and small passages) with carb cleaner and Q-Tips and then reinstall. Test for functionality. It could simply be dirty.
How do you clean egr passages on 1998 mercury mystique?
Remove the egr valve, but be careful. The bolts can break easily if rusty. make sure the vacuum hose is clear of obstruction and try and spray some intake cleaner into the intake where you removed the egr valve, it may take some time with a small tool to work through the clog until the passage is clear
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.
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 clean 1996 Chrysler cirrus egr?
You can't really clean the EGR valve. If it's faulty, it simply needs to be replaced. -Jesse
