#25 of 43 Mazda Millenia problem...
Jan 04, 2010 (11:57 am)
My friend has a 2002 Mazda Millenia and he went out to start it for his wife - it started fine but when he turned the heater it died. He tried to started it again and it sounds like it wants to start but it doesn't. It has been a couple of weeks since it was started and we have just recently had temps in the teens and single digits.
Could the gas line be froze?? Battery issue?? or Electrical??
#26 of 43 Help with codes on Mazda Millenia S
Apr 22, 2010 (11:39 am)
Can anyone help me... I have a 2000 Millenia S and it is running like s--t. It runs hot every once in a while and when I'm on the highway driving aprx. 65 miles per hour it is sputting/missing almost like gas isn't getting to the right place. The check engine like is on so I brought is to a local shop and they ran codes and what showed PO115, PO431, P1790. The guy told me he doesn't work on this type vehicle so I'm stuck. any ideas of what the codes mean and how I can get it fixed? Also, TCS OFF/ TCS light comes on every blue moon. sometimes only TCS OFF, sometimes both.thanks

Hey I know it's been a while since you posted this but.... I have a 2000 Mazda Millenia S with this same code P0431. Same problem as you, local shop told me cat converter but the muffler shop told me it was in good shape, looked new some then another shop said pre-cat... talk about confusion is right. I'm lost and don't know what to do... you can email me at april.bourqueyahoo.com or reply on this post. thanks
#28 of 43 A/C Problem
Aug 09, 2010 (9:02 am)
I purchased my 2002 Millenia S in 11/05. Every year since, I have had the same recurring prblm. The A/C will be working fine and all of sudden you get that stale, humid air feeling and realize it quit. The fan is still blowing but it's not cold air. Sometimes it will cycle and come back on but most times the engine has to be turned off before it will work again. This year it has happened the most which is several times a week. Previous years were like it would be great for several days to a few weeks at a time with no problem but eventually it would happen. The A/C has been looked at every year by a mechanic. 2 times they said the ever popular "Could not duplicate problem". 3 times (including this year) I was charged around 80.00 per visit because they said I was "A little low" on freon but no leak detected. Any suggestions? It's freaken hot this summer in Kansas. HELP!
#29 of 43 Replacing EGR Valve
Aug 09, 2010 (9:15 am)
How difficult is it (for the avg person) to replace the EGR Valve on a 2002 Millenia S? The part is approx 15.00 and the labor is approx 120.00ish. I am willing to try and do it myself if it's not too difficult.
#30 of 43 2001 Mazda Millenia engine noise tapping
Aug 11, 2010 (4:06 am)
I just purchased a 2001 Mazda Millenium V6. with 100,000 miles. It ran good when purchased. Last week I began hearing heavy tapping noise coming from motor when I started the car. When I excellerate the tapping noice would go away or quiet at times. Other times the tapping would get worse. It has got to a point I cannot drive the car because of fear I will do permanent damage to the motor. Has anyone experienced this problem or have an idea of the what the issue could be?

I have a Mazda 2002 Millenia and I recently came across this situation . My CEL came on and prior to it coming on I noticed I was getting a rough idle at times , actually a knocking every couple of seconds , would do it three or four times as I wait for green light . Also was getting a sluggish acceleration . I stopped in at a local Autozone , they plugged it up and a code P0431 came back / Catalyst System . I simply added Iso-Heet/Water Remover and Lucas Complete Fuel Treatment . After driving 25 miles the car runs smoother and no more CEL . Hope this may help anyone before running to a shop and throwing money away . Thank You .
#32 of 43 01 Millenia w/codes P0421, P1250, P1522, then later codes P0421 and P0400
Mar 18, 2011 (7:09 pm)
ok, my car's been in the shop 3 times in the last 3 weeks!!! First codes P0421, 1250 and P1522 came up and the shop did some replacing of a couple valves or something like that then 10 miles into my drive home my check light came back on so brought it back and they decided that it was 2 o2sensors and 1 catalytic so they replaced those and then 20 miles into my drive it comes on again and this time they didnt give me any codes, just told me that the puter must be reading that the old unreplaced o2 sensors are bad now and that i should replace those!!! So instead I went to autozone and was told that it was now only code P0421 and i should look for leaks before anything else. They reset the computer and it was great! No check engine light for 2 days! Then tonight... BAM!! It's back on and auto zone says its P0421 and also P0400. So now i have a whacked catalytic converter and a egr problem!??!??!?!!??!! PLEASE SOMEONE OUT THERE SAY YOU'VE BEEN THROUGH THIS AND HAVE ANSWERS!!!!! PLEASE!
#33 of 43 2001 mazda millenia S
Sep 22, 2011 (10:17 am)
Iv reached my limit with this car maybe someone here can help me out.
Car idles perfectly but when put into drive, it reaches approx 2000 rmp the engine bogs down and doesn't allow me to speed up, going up hills is worst most of the time i end up slowing down. Mazda did some work on it then suggested it was the supercharger... Fail... I purchased a used supercharger and after the swap out the problem is exactly the same.. So to add to the mess, I attached a diagnostic computer to my car which I have done plenty of times before... except now when I unplug the cord (specifically the cord) from my car. It stalls out and will not turn back on until at least the cord is plugged back in. Iv tried all forms of plugging it in and out with and without a battery no luck
When the car bogs down... sounds like its missing, with a crackling noise.

My 02 Millenia S (Miller cycle engine) CEL mystery was eventually fixed by replacing the gas cap. At my dealer it was $125 (don't try using a cheap one from your local auto store; pry open your wallet and use the Mazda one -- apparently there's a sensor that relies upon NOT having a dried out gas cap seal). Go figure.
