B2300 EGR Code

[T-Bone]

Help!! I purchased a 2000 Mazda B2300 with a 2.3, with 110,000 miles on it. The servise engine soon light came on so I took it too the local parts house, they read the code it is a P0401 egr. I went to remove the egr valve and the fitting that attaches to the exhaust system is frozen on there. My question is this, does anyone know if this pipe is a dealer part or can it be purchased aftermarket also. I can see the likely hood of destroying this pipe/fitting and would like to know how or where to get the replacement part if I need it. Attempting to remove this reminds me why I hate working on anything attached to the exhaust sysytem! Thanks for any help.

heat it really hot with a torch and then try to move it.

removing egr is just that you go have a light engine is always turn on

I had the same deal a few weeks ago on my 2300. I couldn't get the pipe off. I went and did some research on line and it is a common problem. I read many times to take some carb cleaner and spray in the valve. Then get some pliers and manually move the valve shaft up and down to free it. Then i disconnected the battery for a minute to reboot the computer. Worked like a charm and turned off the engine light. Also saved me $50 on an EGR valve i didnt need.

Hope i helped.

I'm heading out to the garage now to start working on it. I will try this first. Thanks for the help, I love this site and all of the help that is available. I'll post the results when I'm finished so maybe it can help someone else.

Problem solved! Replacing the DPFE(Ford) EGR pressure sensor on my Mazda pick up, and clearing the codes, it repaired my problem of the service engine soon light on accompanied with, hesitation, intermittant high and erratic idle, high idle between gears. Oh yeah a code P0401 also. While removing the sensor, I broke the larger of the two vacuum lines going to the sensor. They were very dry and brittle, so I also replaced the vacuum lines, I cleared the codes, test drove and Wallah never ran better. Thanks to everyone for the help figuring this out.

Its not frozen on(unless your in the middle of a snowstorm right now) The EGR nut is not a typical hex like other nuts. Ford cranks down on this badboy and its kinda oblong. 1 1/8 wrench will fit it if cut in half. The other option I used on a crown vic was an air hammer with a v notch in the flat tip. I hammered it off so to speak. (unscrewed it, didnt break it) The wrench idea is a little easier and if you have body lift makes it a little easier to access.
