Thank you for creating and posting this video, I just purchased a used CX-7 and only a week after the purchase the "Check Engine" illuminated and it was the P0401 code. Your video was extremely helpful to me allowing me to clean the EGR myself and saved me over $400+ having the repair shop do it. Thank you and I really appreciate the video.

You have to clean the tube. It's a small diameter and that's what gets plugged and restricted on these. Valve cleanings are essential as well.

This is an excellent video. What would make it better, might be showing the speeded up (2x) sequence at normal speed, and breaking this up into two parts - assembly and disassembly. 2x the hits, and a little more digestible a piece at a time. Nonetheless, even as is, a great primer on how to do this that no factory repair manual can fully replicate.

I can only imagine how your knuckles are going to be after this job. Great work by the way and thank you so much for sharing.

Good job. Some more advice to others. I had PO401 code on 2004 Mazda 3S. First thing I tried was to "tap" the plastic motor drive head several times with large screw driver handle. This seemed to dislodge some crap in the valve and the EGR valve seems to be working fine for now. If code happens again I try to remove the motor head on the valve without removing whole valve from car (far less work than removing whole EGR valve. Then clean and exercise valve piston/ motor head the best I can and reassemble. Don't want to remove whole EGR valve and pay for new valve if I can avoid it.

I see that you are both a Master Videographer and very good tech. When the shop says they cleaned something and charge $150, I never realized how much STUFF must be removed and replaced to get to the part! Good Job!

[@christophercates5257]

The valves aren't what get clogged it's the tube.

Thank you for your video, really helped me.

I have a 2007 cx7 it doesn't have spark plug wires like the kind with distributed caps, instead it has ignition coils and the wires that go to that are all taped up, so if one of those is bad you have to splice another one on

@OldSoulMillennial, Thank you so much for the video! I need to make the same procedure myself and was wondering how hard it will be.

[@Funrunner008]

Could you you use some MAF cleaner in the plastic part?

[@AP-bo1if]

was wondering I have a cx7 2.5L auto and the throttle is too sensitive from stop it's like you apply 5% throttle and it goes to 50% throttle open. any ideas? throttle position sensor? acclerator pedal?

I know older video, but how long overall did this service take you? Estimating is fine.
