The EGR valve helps your car more efficiently and completely burn fuel
by recirculating a portion of your exhaust and running it through the
combustion process again. When the EGR valve goes bad, it must be replaced.
The EGR valve, or Exhaust Gas Recirculation valve, is a vacuum controlled valve which allows a specific amount of your exhaust back into the intake manifold. This exhaust mixes with the intake air and actually cools the combustion process. Cooler is always better inside your engine. The exhaust your EGR valve recirculates also prevents the formation of Nitrogen related gases. These are referred to as NOX emissions, and are a common cause for failing emissions testing. Unfortunately, your EGR valve can get stuck, causing NOX gases to build up. You'll know if your EGR valve is stuck or malfunctioning because your car will experience symptoms like rough idle and bucking on acceleration.
Here is a picture of where the EGR Valve is located (Accord 1999). Replacing it is fairly simple and straightforward. A vacuum line and a couple of bolts. You'll see what you have to do when you look at it.
If you are replacing the EGR Valve due to the Check Engine Light (MIL) being on with a DTC P0401 then I suggest contacting your Honda Dealer. There was a Product Update Campaign (PUD) in the fall of 1999 that corrected the problem.
Another times, the clean is the solution...I hope help yoiu with this. Good luck, and remember rated this help.
