#1 of 24 EGR problem with 1999 Mazda Millennia by kaczjones Mar 23, 2007 (12:10 pm)
I have had an EGR problem with my 1999 Mazda Millennia since the first week a I had purchased it in 2002. They replaced the EGR valve and knock sensor multiple times. They even drilled bigger holes in the engine and my engine light continues to remain on. Now the engine light is blinking. Any suggestions? The dealership where I have been taking it to told me to ignore the light. The only thing is $3000.00 later I have the same problem but now can not drive it because the light is blinking. The dealership told me now I have to replace a part that is going to cost around 2600.00 just for the part. Please help with any advise!!! I can not trade it in or drive it!

Replying to: kaczjones (Mar 23, 2007 12:10 pm) You might also want to post this in our Technical Questions discussion. It's not limited to the Millenia and I think you'll find more gearheads hanging out there than you will here.   But we'll wait to see if someone here can help as well.   Good luck.

Does anyone have the layout for the oxygen sensors for the 99 mm S. I need to find the bank 2 oxygen sensor.   Thanks for your help

Replying to: kaczjones (Mar 23, 2007 12:10 pm) I really don't have any suggesstions other than write a letter to the main boss of Mazda. Its rediculous that you can not trade or drive the car. A part that small should not cost so much. I would expect that price on a major part (engine, Tranny...) I am having similar problems with my 2001. I can not seem to get the check engine light to stay off. I have replaced the EGR Valve, put fuel system cleaner in it and cleaned out the ports. I had a mechanic look through the whole emissions system and he says everything is working as it should, but the light continues to come on. I am sorry for your bad luck with the car. It seems many owners are haveing similar problems. You would think Mazda would do a recall, but you know they are in it for the money.

Replying to: jazzyman26 (Aug 08, 2007 6:10 pm) I have had a 1999 and a 2000 Millenia. The EGR value issue is a big chaotic problem, yet with a simple solution. If you take the intake off the throttle body, and remove the four screws that hold the throttle body on and remove it also. You WILL see a really clogged hole in the bottom. If you take some engine cleaner, and spray it in it will break up the build up. I usually straighten a paperclip and clear the hole that way, but I think it would be better to instead of letting it fall through, picking it out. The check engine light will stay off, until there's another buildup. It is hardly ever the EGR Valve. Only few mechanics know this, so when they replace the EGR and it still does the same, you are all confuse. Wierd enough, you may also have carbon deposits in your exhaust, please don't check it while it's running. LOL
#9 of 24 For those with the TCS off and intermittent stalling problem....a solution by megaquark Oct 07, 2007 (1:07 pm)
Had the same problem a few years ago. There is a EGR sensor (or something like that) that is up in the middle slightly to the passenger side right up by the firewall. It plugs into a harness. It has a Mitsubishi emblem on it. Take it out. Start the car. Always have the TCF off light on and the engine light, but no more stalling.   (note, this is a completely different problem from the previous one I just posted- I felt that if I was asking, I might give something back)   Apparently this car has a history of a faulty computer that turns the TCS off light on when it shouldn't. So the TCS off light is misleading. It has nothing to do with the TCS - it's emissions. Removing the sensor has solved the problem on 4 others that I know of. Happy driving!

Replying to: kaczjones (Mar 23, 2007 12:10 pm) same problem here 99 Millennia S. have been driving with the Check Eng Light on for almost a year. Recently it started to blink. took it in to Firestone for Diag; they told me i have PO-431 Ignition coil #4 mised fire and typical O2 sensor issue. I plan to chang my spark plug this weekend. Don't spend money on O2 and anything more than a Thousand dollars repair just ignord it as long you have AAA just drive this car and have a good time - I really like this car but have no intention to upkeep it, cars are losing proporsition from day one. just gas and zoom.
