UPDATE:

After diagnosing the error code, the dealer said it was a faulty camshaft timing gear assembly. They said there was a TSB on this issue and they put the part on order for replacement.

They advised it'd be fine to drive for a few days until the part came in.

 

That was the first thing they did to mine when I started having the light problems... it did not fix the problem.

The actual fix was a "VVT gear"
My invoice said:

14064 Code P0012 Cam position over retarted tech line case TA061220151 Recomend Replace VVT gear removed timing chain timming working properly now cleared code returned to customer.

^I know this dosen't make much sense it's just what they typed up on my invoice.


Here was my original post

Nice. Well, at least I'm 'in the system' now...and I really don't mind having a new part installed. If it doesn't fix it, I'll just take it back. They reset the light at the dealership and I drive it for about 15 mins at varying speeds on the way to work this morning and it hasn't come back on yet....

 

After taking a look at your problem, I've noticed that mine might be different. My daily commute to/from work is 20mi 1-way... When my light(s) came on, they continued to stay on continuously until I took it to the dealership this morning...so...

I guess we'll see.

Mine's an '05 and yours is an '06...the service manager said that there was a TSB fix for my issue, too...maybe it's different on an '05 for some reason. Either way, I can't find a TSB for an '05 that seems to fit the problem...so heck, I dunno...

 

the lights just came on this morning on my wifes xb. taking to dealer to be safe in an hour. hope its something they can fix and we can still drive the car this week

 

Just had this happen to me also. VSC, TRAC OFF, and CEL came on. I'm freakin out as I pull into my garage.

I figured it was because I was listening to my bass uber loud (chest thumpin, hard to breathe kind bass) and it must have tripped something up.

I just disco'd the negative battery cable and reconnected. Voila! Fixed. Heh, thats when you know you have a kick **** system.

 

Occurred at 65,200 on my '05 xB. I just brought it in today. The Scion tech said the CAM gear assy had cracked and the timing was going out. Good thing it lasted the trip from Sacto to Concord here in CA. Full warranty coverage on the car saved me on this. They're going to check the whole system for warpage. I thought it might be a O2 sensor or the gas cap being the culprit. Anything that affects the power output of the engine causes the sensors to turn the lights on if it doesn't self correct.

I like my Bento Box. Not that it smells like sushi inside...

 

Got this yesterday.....ScanGauge is reading P0012 so it looks like it's going in the shop :-(

Used the ScanGuage (great piece of equipment!) to clear it once but returned after 50 miles.

 

damn lights just came on for me too! '06 with 27,650 miles

 

turns out it was the gas cap. gotta love SL for the info. saved me a trip to the dealer

 

HOW DO YOU RESET THE LIGHTS? who knows the prosedure?

 

found this but it did not work for me. so somthing mite really be wrong

car @~31k

I have had this problem intermittently since January and I finally was able to find a good dealer to service it after I moved.

They ran the codes, said there was a problem in the camshaft (i'm not sure if it was damaged or if it was a faulty solenoid). I had it fixed under warranty (they had the car for a whole day).

Either way, this morning, one day after repair, the lights came back on. Still no reduction in performance or anything, but I'm wondering if my cars suffering one of the other symptoms (MAF sensor, etc). I'd like to think that they got it by pulling the codes, but that doesn't seem to be the case.

Back to the dealer.......

 

Same here....'05 xb. The girlfriend just called me stating the lights just came on when she turned it on. We are going to go by the dealership tomorrow. I will try to keep everyone updated. Has anyone had any trouble getting the dealership to fix the issue(s) under warranty for this? I have the 6 yr platium one. I know I am over for an oil change but thats about it.

 

Should have followed up on my last post...but I think Toyota solved the problem for me back in August (knock on wood).

Originally they though it was a bad timing solenoid related to the VVT-i system. After changing the solenoid...well as I said, the lights came back to I took it back to them. They opened it up, replaced the entire valve (why they did not do this the first time, I don't know) and since then, no issues.

I had around 33k on the car at that point and they covered it completely under warranty. i even got a loaner corolla for the day on their time. Sloane Toyota in Devon, PA.

 

I see a lot of people saying it the cam/timing/VVT. What did you tell your dealership...just these lights came on was does it mean? or did you say hey I heard other people have had these types of issues?

 

Well...she turned back on the car to come home and the lights were gone. I am going to keep an eye out for them though.

 

Update: About 20K miles later, I haven't seen these lights pop up. Should I still have it checked though? I know some people are running on stock stuff, me on the other hand, had a short-ram intake that made my MAF sensor dirty.

Do you think my lights will pop up again? Im scared.

 

I just told the dealer the lights came on. I read all sorts of stuff here about how it may have been related to the MAF, etc, etc...but it ended up being the valve as I described.

If that is indeed the problem, the lights are going to come and go until its fixed. There's a TSB out on it, and if your car is still under warranty they should take care of it.

 

My lights came on in the summertime. Took it to a friend and the code cam up as cam shaft something?

Was fine after he reset them.

Last night they came on again. My wife has the vehicle today and she sadi they went back out.???

Should I take it in?

I have 54000 miles on it. 2005 xb
