These 3 lights came on VSC,TRACK OFF, CHECK ENGINE all at the same time checked gas cap, can someone te where I can find the wiring diagram for the obd so I can do the paperclip thing to turn off and reset the lights

Check for cracked vacuum line coming off throttle body towards firewall...there are 2 sections with a control valve in the middle. Front section was toast on mine. Replacing that line turned off all the lights immediately. Obdii reader was saying evap code.

The small one between eng cvr and intake going to the little blue valve under the stb.

Make sure your battery's not toast, also. Mine recently started doing that and after a stop at AutoZone they checked my battery and it was super old and not holding a charge. After replacing that, all of the lights went away.

Honestly, it could be many, many things, but maybe one of these suggestions will give you a solution.

Where did you get the hose ? Also where did you get that battery hold down ?

Disconnecting the battery will only temporarily get rid of the lights. After driving for a while , if there is a leak , they come back on.

04toaster- I have learned so much about my car from your posts alone! I replaced this wire/piece on my old xB but the codes were catalytic converter/exhaust related and it didn’t work. Current xB is throwing evap codes strictly and I’m gonna give this a whirl again!

Hose from auto parts and battery tiedown is aem and think they may still be on ebay or just google aem battery tie down 2005 xb....silver or gunmetal.....oil cap is also matching aem

I have the same lights, but it's just my camshaft position sensor. Maybe check that..?

Thank you I will check . What is the eng cvr ?
I am now getting a code PO012 and it tells me Camshaft timing is retarded

 

[04_Toaster]

Eng cover is the carbon fiber thing with vvt-i on it in the pic above. Camshaft code might be from vvt-i sensor being dirty or failing....on passenger side of motor facing wheel well with electric connection going to it.

Checked for vacuum leaks did not find any put in new oil control vavle and reset lights. lights came backlon after 100 miles

update I have got new gas cap, oil control valve and changed the oil . rest lights and they all came back on after about 100 miles. HELP

When you say "oil control valve" what are you referring to? It wouldn't happen to be what's in the photos I'm including would it? I hope it's not, because it might make what I'm imparting here moot, but I will go forward anyway. I believe this is called the "vacuum control valve". I had trouble with the "3 lights" for probably a year. Turned out to be a combination of 2 things. #1 I found that if you tighten the gas cap more than ONE click, it will set off the lights. #2. I discovered that the VCV on mine was not opening/closing properly. I ended up shooting some penetrating oil into it & direct wiring it to "click" off. & on. Those two things eliminated the problem. Now once a year or so I pull the vacuum lines off the VCV & shoot some penetrating oil into the valve with the engine running and haven't had an occurance for several years. I've owned my 2006 xB for 7-1/2 years now.

Thank you for the info and yes i was referring to the oil control valve but I will try what you suggested. The 3 lights go off and come back randomly for not reason been keeping a journal of when they come on and when they go off so far I noticed they will come on Everytime I fill my gas tank and go off when I hit 3/4 of a tank if I remove and reinstall the gas's gap . Then it comes back on again about Half a tank . And if I do the gas cap it make no different . It has a mind of its own

You're quite welcome...I just hope it might help. The code that triggers the "3 lights" doesn't really affect the performance of the car, but they affect my "psyche" while driving...It's like, I don't like my car as much while they're on. Anyway, I did think of one other thing since my original response that seems to affect the 1st gen xB's. When you fill up don't top it off too much after the initial automatic "click-of" of the nozzle. During my research I found there is a reasonably documented theory that the design of the overflow tube built into the filler "neck" allows gas to enter the charcoal canister, saturating it with raw fuel, if topped off too much.. Some say it ruins the canister...my personal theory is since the purpose of the charcoal canister is to store the "fumes" emitted from the tank, the overflowed gas in the canister will slowly evaporate and be evacuated by the vacuum removal system. That's what the VCV I pictured in my original response does...it cycles and draws "fumes" out of the charcoal canister, directing them into the intake air stream. Since the raw gas will take awhile to evaporate and be removed, it could easily throw the code(s) to trigger the "lights". Just something else to consider. Anywho...good luck, I hope you get it resolved.
