I think there is. One is normally open and the other port is normally closed, depending on the application.

I think the one pointing down is the one that remains with nothing plugged in. I accidentally put the hose on the bottom of the solieiond and it over boosted. Put it on Lethe side and all good, I was just wondering of anything went to the bottom plug as mine looks to have white thread tape around it!

Easy way to tell is to blow through the top one and see where the air comes out. That's where the hose goes because they're set up so if the solenoid fails to power up they will let air through to open the waste gate.

hey guys. This is my fist post. I would like to say thanks first up. This forum is a great, a wealth of infomation on the mighty xr6ts. I recently purchased a ba 04 stock (with k an n filter) 5spd man and under 100kms. Car is a treat to drive. Having read up on cleaning the boost solenoid and throttle body and reading some of your replies to it, I thought hey I wonder if I clean mine if It will bring back any power they may have been lost over the last few years of the car.

So off I went and gave the throttle body a clean aswell as sprayed some wd-40 into the boost solenoid and the hose attached on top. I took it for a spin but it was raining so it was only quick. After a day or so once it dried up we went out for the day and it seemed to me that the boost was low. It wasnt kicking as hard as it used to. It feels like there is hardly any in first gear and the other gears it just seems to be a lack of boost. It still goes hard.

To remove the solenoid I did have to remove the battery but I dont imagine it would have any ill effects with this sort of problem. As far as I can tell all the plumbing is on tight.

Usually I can hear the BOV and a bit of turbo flutter. Now I really only hear some fluttler but not as much as I had.

So my question is has anyone else come across this? My first guess is that I`m loosing boost due to the waste gate venting the exhaust (so that is peharps to solenoid being open??) so I`m going to try giving the soldenoid another clean and tripple check all the plumbling.

So I`ll let you know how I get along.

Any thoughts or ideas would be much appreciated.

:sungum:

Have you checked the hoses on the solenoid...maybe one came off or loose from WD40...I had to put a hose clamp on one of mine cause it was always sliding off from the lubricant.

KWIK F6. From what I can see its still on. But I will tripple check it tomorroow. thanks for you reply.

Taken from another post:

Thanks for the info went and cleared it this morning and found it still has no power might as well drive the yaris around lol has another good look under the bonnet and found a large crack in the rubber boot on top of the throttle body ( the one with the two large clams) so I'll be shopping around for one today any ideas of who might have one on a Sunday? Has anyone had this happen before? Anyway soon as I change it I'll let you know if all the power is back thanks again

It's in the top right hand side

XRTFG6 ended up swaping this with a 13bk part and problem fixed. Will check tb tomorroz.

Seems to be all good now. I pulled everything off that I did the other day and just repeated the same steps and put it all back together. 1st gear boost is back and the boost kicks in a liltte better then before. Gave the solenoid a real good squirt with wd-40 then cable tied the hose on. Checked all line to turbo and wastegate. Took off all the piping from the hot side and tripple checked it went back on correctly. I noticed that when I put the plumbing back for tb that I may have not put it to how it came off (how it had moulded to tb) also the first time I was getting at the solenoid I hadnt removed the hotside piping post intercooler so I took that off as I said. It was a little slippery inside around seal. Gave it a good clean and put it back on. So where my problem was I wont know. Maybe I havent gotten rid of it and it`ll be back tomorrow but for now she seems all good.

I take it that throttle body hose was your problem. I know it happened to me and I had the same issues as you. Seems like a common problem.

It could of well been. From what ive read the boost solenoid doesnt seem to muck around where as the plumbing is a little more prone to. There was a leak somewhere 1st was like it was an N/A the other gears there was boost but very little compared to what it was. It raining again in sydney so the roads have been wet all day so not really a good test cause I kept spining. hha.
