#3559 of 4030 Hold Light/Knock Sensor
Dec 29, 2005 (5:31 am)
I purchased my Mazda Millenia back in 2002 with 49,000 miles on it. I had a few problems frame wise that the dealer fixed but the engine and transmission were immaculate. But recently I noticed around 90,000 miles that my Hold Light (transaxle problem according to the manual) would tend to go off and on when it felt like it. I would drive for a few miles and as soon as I came to a stop and put my foot on the brake the light would disappear. I took it to the Mazda dealer in my state (NJ) and they said my computer determined that I needed to change my Knock sensor, EGR valve and one other part but I can't remember. I procrastinated for a while and now my car is losing power and the light comes on more frequently now. Now at 97,000 miles I can be going 45mph and my RPM needle goes haywire like the car is racing but it's not. I took the car to another outside mechanic and he told me the reason my car is making a rough riding noise is because something is burned out in my transmission. Needless to say the look on my face when he said the word transmission damn near gave me a heart attack. I did a search online for the Knock Sensor and found one at a reasonable price of $74 (jcwhitney replacement parts) and just because I read in other forums that I might need to change my O2 sensor I bought one of those as well. The only thing is I read that Mazdas have more than one O2 sensor and I don't know which one to replace to get better gas mileage. Anyone have any suggestions or other problems like this?? I'm hoping once this piece comes that my problems will be solved and I won't need to replace my entire transmission.
Also does anyone know how much EGR valves run??

As I read your post I get the feeling its my Millenia you are referring to. I also have a 2002 Millenia and am experiencing the identical symptoms. I have 86k miles on it. Two weeks ago I brought it to the dealer and he said I needed a tuneup-cap, rotor, and plugs. They wanted over $300. I paid the $69 diag. fee and did the work myself for less than $80. The only reason I brought the car to the dealer is because I have the extended warranty. Well after doing all the work the CEL light is still on and yes my hold button light flashes and my tach dances. Just yesterday I brought the car to a different Mazda dealer who said the codes are referring to something with my EGR system.
Hopefully I'll find out more today and let you know what the outcome is. I can only hope its a covered warranty expense.
Talk to you soon

Thanks alot...I'm still waiting on my part to come so I can take it to the mechanic and get it changed...after reading everybody else's posts I feel like Mazda needs to be paying for these repairs instead of us!!
I'm taking it to Autozone and getting it checked out so I too can know exactly what the codes are. I had the list from the Mazda dealer but lost them. At least if I take it to Autozone I dont have to pay for the diagnostics test...that's $89 I can keep in my pocket toward a future repair....
#3563 of 4030 Heated Seats
Jan 07, 2006 (10:43 am)
Has anyone had trouble with their heated seats on the Millenia? I am told that I have a split in my line. This is the 2cd time they have gone on me, and I only have 37K on the car.
#3564 of 4030 What are these holes for??
Jan 09, 2006 (3:33 pm)
I have 2001 Millenia P. To the rear and bottom portion of the rear wheel wells there are 3 vertical holes about 2 inches apart. This is just inside of well and holes are on painted part. What am I missing?? Almost looks like a mudguard should be bolted on there. Do you also have these holes?

Jan 10, 2006 (9:45 am)
I had the same issue with my '99 Millenia, took it to a shop and they opened up my Mazda, and behind the radio controls, theres a switch that seems to control the vents or something that brings in either hot/cold air... apparently the switch was broken looks like a little box, (210$? or so for a new part from a mazda part store, none in stock go figure) Anyway at first he just switched the vent to only give heat and no more cold air, then was bored and decided to take the switch apart. not sure what he did after that but now I have heat and cold air, and I only had to pay labor, I'll ask him if he remembers the name of the part and update when I can.
Hope this helps.
Mazda parts are expensive..

Okay finally 6 days and the dealership has finally come to the realization my PCM needs to be replaced.
Fortunately, its under the extended warranty.
Lets hope this works.

just knowing the actual code #'s is half the battle when it comes to diagnosis. For instance, some code #'s that refer to the O2 sensors do not indicate a faulty O2 sensor itself, but a related problem.

You are so right cam and that's just why I'm heading to Autozone to get the codes. That way when I do present the problem to the dealership they can't give me the runaround. I was thinking of changing the transmission period but then I was thinking about a friend of mine who had problems with her trans. and had it rebuilt. She had to have it replaced 4 different times...I honestly don't think I wanna go throught the headache
