street3890 Posted February 26, 2008 Report Share Posted February 26, 2008 My check light has been on for about 2 weeks now. Prior to that my mech. cleared the light and the codes came up as P0431 (catalytic converter problem) The problem that is random is the one where my tsc off light comes on (without pushing the tsc off button) and then i can't go above 2500!!! I have no clue what it is and it happens randomly. Help please!!! I know last time somebody said it might be something with a solenoid valve or something but i'm not sure what to look for and i can't follow that diagram for shit!!! [/img] [/img] thats 2500 rpm's, the last time this problem happened was about 4 months ago, and it has just happened twice in the pat 4 days!!!

street3890 Posted February 27, 2008 Author Report Share Posted February 27, 2008 I was searching around on google for a solution and a bunch of people have had this problem and it seems that most of the problems were vaccum leaks near the air bypass valve, i'm going to try and check them tomorrow when i get home from school.

street3890 Posted February 27, 2008 Author Report Share Posted February 27, 2008 And i've been researching for the past 2 hours or so on this topic and this has happened to ALOT of people with millenia's!!! Quote Link to comment Share on other sites More sharing options...
Matt64341 Posted February 27, 2008 Report Share Posted February 27, 2008 It is almost definitly a vacuum problem. If you get the vac diagram in the tech section and trace the lines and look for broken tees and lines that may be damaged, you might get lucky and find an obvious problem leak and can replace that section of hose. If you cannot find anything, you will need to start replacing the lines, which is not really that hard as long as you take your time.

street3890 Posted February 27, 2008 Author Report Share Posted February 27, 2008 Ok, thanks alot. I just want this problem to go away. Quote Link to comment Share on other sites More sharing options...
Matt64341 Posted February 27, 2008 Report Share Posted February 27, 2008 I have replaced a couple broken tees before, and just a couple days ago I did all the lines. If you have leaks, you will definitely see an improvement in how smooth the engine runs and slightly improved acceleration if your having any hesitation in the 2000-3000 rpm range. It is not too hard of a job to do as long as you know what to remove. Quote Link to comment Share on other sites More sharing options...
street3890 Posted February 27, 2008 Author Report Share Posted February 27, 2008 Ok, thanks again and yes if i don't find anything tomorrow then i'll prob change them all on saturday with my dad. Quote Link to comment Share on other sites More sharing options...
street3890 Posted February 27, 2008 Author Report Share Posted February 27, 2008 It's so hard to find and look at all of those hoses!!! I can't get to half of them!!! Somebody should come to my house and find it lol Quote Link to comment Share on other sites More sharing options...
street3890 Posted February 27, 2008 Author Report Share Posted February 27, 2008 If i dont find any cracks or splits, is there another possibility? I've also heard that it could be a bad mass air flow sensor. Quote Link to comment Share on other sites More sharing options...
street3890 Posted February 27, 2008 Author Report Share Posted February 27, 2008 I'm fucking pissed, i love this car and i want this problem gone NOW lol alot of the problems i've read about are leading to either vac. leaks/splits or something with the ABV. Something about some code 82 thing. Vacs under the intake manifold, which i have no idea where it is. I'm going to my mech. tomorrow to get the codes pulled and if the come up as p1540, i'm gonna let him keep te car and check the vacs. and EVERYTHING else related to the abv lol Quote Link to comment Share on other sites More sharing options...
Renboy Posted February 28, 2008 Report Share Posted February 28, 2008 I'm only 600miles away if you want to swing by. I guarantee I'll fix it. Quote Link to comment Share on other sites More sharing options...
street3890 Posted February 28, 2008 Author Report Share Posted February 28, 2008 That's too far for me man lol but what do u think it is, help is appreciated. Quote Link to comment Share on other sites More sharing options...
Renboy Posted February 28, 2008 Report Share Posted February 28, 2008 Either vac, or one of the abv solenoids. No doubt. Quote Link to comment Share on other sites More sharing options...
street3890 Posted February 28, 2008 Author Report Share Posted February 28, 2008 How do u check the abv solenoids? Cause i haven't found any vac leaks/splits yet. And where do u think the vac leak would be near? Quote Link to comment Share on other sites More sharing options...
Matt64341 Posted February 28, 2008 Report Share Posted February 28, 2008 If you replaced the vac lines yourself it might cost you $30-35, you'll pay a good $200-300 more in labor if you let your mechanic do it. Then if you turn around and it is your abv that is the problem, you'll be out even more. Quote Link to comment Share on other sites More sharing options...
street3890 Posted February 28, 2008 Author Report Share Posted February 28, 2008 Yea i know, but is there a way that i can check if it's bad? Quote Link to comment Share on other sites More sharing options...
Renboy Posted February 28, 2008 Report Share Posted February 28, 2008 Print the vac diagram that I posted. Then check/replace the lines one at a time. Do this even if they're not cracked...call it preventative maintenance. The check the solenoids, they should read between 30 and 90ohms (I've seen some that have over 120 and still work, but those won't work for long). Then apply 12v to the terminals on the solenoids, if you hear a click, then they're okay (assuming resistance is within spec). Quote Link to comment Share on other sites More sharing options...
street3890 Posted February 28, 2008 Author Report Share Posted February 28, 2008 How do i check the ohm's? With what? And i'm not sure what they are exactly? Quote Link to comment Share on other sites More sharing options...
Matt64341 Posted February 28, 2008 Report Share Posted February 28, 2008 You need a multimeter, you can get them at RadioShack or Wal-Mart. Quote Link to comment Share on other sites More sharing options...
street3890 Posted February 28, 2008 Author Report Share Posted February 28, 2008 I went to my mech. and the codes came out as 1525=abv vent and 431=something with the cat. I left the car there and he's gonna check for leaks/splits/cracks and whatev. Quote Link to comment Share on other sites More sharing options...
street3890 Posted February 29, 2008 Author Report Share Posted February 29, 2008 There were no vac. leaks/cracks and my mech. doesn't have enough experience and notes on the MCE for the s, so im going to mazda!!! Quote Link to comment Share on other sites More sharing options...
