Your 1999 Mazda millenia S TCS light stays on and will not turn off and it stops your car from going over 2500RPM what is it?
vacuum/vent solenoids
How do you replace the abv vent and abv vacuum solenoid valves on a 1997 Mazda millenia s?
open hood locate the egr valve next to it is a row of 4 solenoids. the second from the right is vent, the fourth is vacuum they clip on, but you will probably break them the first time you remove them. then, you will see how they attach.
What would cause a 1995 Mazda Millenia type S to stall when RPM hits three or four and you have to turn it off and on to keep going?
mine done the same thing it was the camshaft position sencor i dont think so. more than likely your ce lite is on, and tcs off/tcs lites, too. car is going into "limp home" mode. if you pull your codes, probably 1525/1526 and 1540, which is the vacuum/vent solenoids, and the abv circuit. replace the solenoids, change out your vacuum lines.
Where is the abv in Mazda millenia?
pull off the plastic cover that says miller cycle. the abv will have a yellowish vacuum "hat" on it, right below about where the 'cycle' word is. if your miller cycle cover is missing, then the abv will be on the back(driver side) of the engine, right in the middle. at the very end of the intake. you will see the yellowish vacuum dashpot on the end of it. but, that valve never goes bad. if you are getting 1540 codes, it is most likely vacuum or vent circuit/solenoids(p1525/1526)
What does code p1525 p1540 mean on a 1999 Mazda millenia s 2.3?
what does the code p-1525 1525 is the vent solenoid circuit. it usually is with 1526(vacuum) and 1540(abv). there are a bunch of answers to this, and this problem is very common in the 2.3. sometimes, this is also accompanied by the car going "limp home". tcs off/tcs lites come on, and car wont rev over about 2500. it feels like fuel cut. there is a row of 4 solenoids right next to the egr valve. the vent is the second one, the vacuum is fourth. you should change both. some will say first check the vacuum lines, and they can be a problem, too, but i am sure it is the solenoid.
What does code P1526 mean on a 2000 Mazda millenia?
Trouble code P1526 means: Air Bypass System actually, this is the abv vent solenoid circuit. you must have a 2.3. the vent solenoid lives on the right bank. next to the egr valve, you will see a row of solenoids. the vent is second from the right(KJ03-18-741A). you can ohm the solenoid to see if it is bad, but i am sure it is. 26 is good, above 30 or 0 is bad. you should also change out the vacuum solenoid(4th from the right, KJ02-18-741A), they both go out about the same time, and they cost the same. dealer only. http://www.tascafordparts.com//index.do this is your best bet for Mazda parts. lastly, if you are going to keep the car, you should also change out the vacuum lines and tees. but this is a big job.
1996 Mazda Millenia check engine light shows egr codes using vacuum tester and pulling vacuum on EGRr valve kills engine Checking egr solenoids vacuum Vent what will turn on the check engine light?
The check engine light is because the EGR 'lift sensor' is showing that the valve is not lifting when it should be, or it is indicating the sensor is open, or the voltage is out of range the lift sensor may be bad, or it's not lifting when it should be (vacuum leak, vacuum switch leak upstream) EGR normally does not activate at idle, or engine will stall (as you have seen). clear the codes, then hook up a vacuum gauge when driving the car. Once the car is warmed up, there should be vacuum at the egr valve at part throttle. If not, the upstream vacuum switch is faulty or vacuum is leaking out somewhere.

What does it mean when the tcs light won't turn off and car starts jerking on a 1995 Mazda millenia?
You have a vacuum leak somewhere in your system. Figuring out where is the hard part. All the those rubber vacuum lines get hard and brittle over time and leak. Replacing them can be hard because of the risk of snapping off a piece of a vacuum tee. The colder the weather the more of an effect the leak will have on your car. It is just a quirk in the Mazda ECU system that causes the tcs light to come on as well. I'm guessing that this is a 2.3. what is happening is the car is going into limp home mode(tcs off/tcs lites on dash, car will not rev above 2500). the pcm and tcu modules are separate, and when pcm detects certain problems, it stops communicating with tcu, and the car goes limp home. most common is problems with the abv. ce lite comes on, and codes 1525/1526/1540 are stored. this is abv vacuum and vent solenoids circuit. the solenoids control the abv, and are connected by vacuum lines. if this is your car/problem, most common is the solenoids, next would be a vacuum leak. to check the solenoids, you need to ohm them. good is 26, if above 30, or 0, they are bad. also, they are affected by heat, and because they are near the firewall, they get a lot of heat. to effectively fix this problem, not only replace the solenoids, but the vacuum lines(21 ft) and tees. this is not a job for the weak of heart. the intake has to come off to get at the vacuum lines
How does the abv valve make a tcs system malfunction on a 2001 Mazda millenia supercharged?
tcs is part of a separate control unit(tcm) attached to the main pcm. when there is a problem with abv, the pcm stops communicating with tcm(transmission control module), and the car is put in "limp home" mode(tcs off/tcs lites illuminate, car will not rev above 2500). quite common in the 2.3, generally, a vacuum line problem. you probably also have codes p1525/26 and/or 1540. first fix the vacuum lines, change out the tees and the lines(about 21 feet), next would be the vacuum/vent solenoids in the back of the engine. one or both of those generally fixes this problem
Why does the tcs light come on while driving in normal weather conditions and car starts to surge like it has bad gas on a 99 Mazda millenia s?
Could be a faulty vacuum hose, that seems to be common problem. if your tcs off/tcs lites come on, and the car wont rev over about 2500(feels like fuel cut) the car is in "limp home" mode. ce lite is on, and codes 1525/1526 and 1540 are stored. it is the vacuum(p1525)/vent(p1526) solenoid circuits, which control the abv(p1540) circuit. they live on a bracket right next to the egr valve. you will see a row of 4 solenoids. the second one is vent(KJ03-18-741A), and the fourth is vacuum(KJ02-18-741A). you should replace them both, they cost about 60 bucks each, depending on discount online. if you go local dealer, expect to pay about twice that. to really complete the job, you should change out all the vacuum lines and tee fittings.
What does code P1526 mean on a Mazda millenia Miller cycle 2.3?
PO1526 is a malfunction detected in the ABV solenoid valve (vent). This solenoid is used to verify the correct operation of the purge control solenoid valve. Although it is not used for anything other than a Diagnostic Support Solenoid it will bring a hard code of PO1526 when it goes bad. The troubleshooting procedure is fairly simple, although the solenoids and myriad of vacuum lines require careful checking to understand where they go. The main thing is to make sure the ABV solenoid valve (vent) is working. Suggest getting the All Data DIY subscription for your vehicle, it is reasonably priced and gives you all the info needed to properly troubleshoot this code. The website is www.alldatadiy.com. Good luck.
