Hello,
I have 2004 Mazda 3 with MIL Codes P2004 and P0661. I brought it to the dealer 4 times and they were not able to fix the problem. They replaced the intake solenoid and intake air shutter valve. I have searched the internet and it seems like I am the only with having these codes. The dealer keeps calling the Toronto Mazda technicians who also have not been able to solve this problem. They keep telling me to come back in 1 month and they'll try it again. So does anybody have any idea what's wrong with the car and/or how I can persuade Mazda to fix it sooner?

After talking to the Service Managerthis time, apparently Mazda is engineering a new intake manifold to fix this problem. The intake manifold is "in production status" what ever that means. Itmust take a long time to build a brand new intake manifold.

 

I also have a 2004 Mazda 3i and talked to the dealership service dept. today... same code (P0661). Unfortunately, my problem is not covered by the extended warranty. My darn luck.

 

Aside from the obvious code. What are/were your symtoms to suspect something was wrong?

 

I am experincing the same thing right now. 3 weeks ago I through the mil for p2004 they cleaned the valve cause the tech said it was stuck open. Well 2 day ago mil back on again. The car is a 2008 and only had 4000 miles when it threw the first code. I did notice the the car has a flutter when it is first started in the morning on a cold day. Other than that no ill side effects.

 

I got sick of the Check Engine light and I traded in my Mazda 3, for a new Nissan Sentra last October.
I do not think they have a fix for that yet because they keep sending me Bulletins for other junk but no fix
for that particular code. What a lemon, I doubt I'll buy another Mazda ever again.

 

Greetings... I am a machanic at a third party shope (private general repair facility), I too have stumbled onto this problem with a customers Mazda3 sedan. Apparently, this type of car is too new for any fixes pertaining to this problem. The only thing machenics could do is just reset the "Check Engine" light over and over again. For owners of this type of vehical: only thing to do is to send requests and numerous letters to Madza, Inc. to speed up the process on fixes, repairs, and replacements of parts.

 

i have an 05 rx-8 the code p0661 came on. i ran my scan tool & cleared it once, to see how long it would last, not long! on my rx it means a stuck or sticking ssv valve, or ssv solinoid, the white one in the center. i hooked up my vacume guadge to the difram valve & it was ok. then i unpluged the siloniod & seen some crud around the pins, i cleaned them & it fixed it. while i was at it i cleaned all three. now after you do that you can change the vacume lines from the ssv & the air motor for the cat warm up to see if it is indeed the ssv one. oh yea after i cleaned them i put batty. grease on the connectors, so far so good! hope this helps someone...
