VSC/Trac Off/Check Engine Light came on
#181
I believe the stock cap can only click once anyway. And getting it on too tight def can't cause CEL to be on.
Are you saying that since you got the car you've been driving with the light ON most of the time?

Well folks - over two years since my last post. Been dealing with the P0012 since then, until...
About a month ago I was tightening my alternator belt when I snapped off the connector on the camshaft position sensor actuator. I had previously checked this and it checked good. Ordered a new one and no more light, no more P0012. Just had to share, maybe this will help someone else still dealing with this.

Hello all ... I registered just to post on this thread. I purchased a 2006 Scion xB back in January, and the 'three stooges' (VSC/Trac Off/Check Engine Light) graced my dash on day 2 of ownership. This forum helped me troubleshoot, and in the end the P0012 code pulled amounted to replacing the camshaft position sensor actuator. I haven't seen the 'three stooges' since.
To add lib, after all the troubleshooting, I drove into my local Toyota dealership and pointed at my dash/lights. The service tech. immediately said 'it's going to be the camshaft position sensor, but we'll confirm it'. My VIN didn't qualify for a TSB, but I'm going out on a limb and saying that the part for my year/gen might've been faulty?

My wife and I have a stock 2005 xB. A few years ago when we were visiting Florida, those three lights illuminated (VSC/Trac Off/Check Engine). My wife & I went to an auto parts place, borrowed a code reader and pulled the codes. Armed with that info, we went to a Scion dealer/shop to get it repaired. The repairman however noticed a loose wire to the Air Flow Mass sensor. He soldered it (with the disclaimer that it wouldn't last forever), cleared the codes and we were good for a couple years. The code came up again right when we took the xB in for the warranty-covered Rear Hatch Handle replacement. The dealer ran codes and tried to sell us on a $600+ charcoal filter repair/replacement. We noticed the loose wire and said "No thanks." We took our xB to a local Houston mechanic, explained the issue and he re-soldered the wire. Well, it's loose again (broken really) so I think it's now time to replace the AFM sensor connection (is it a switch?). It seems that the air filter housing vibrates a lot and one of the 2 wires into the AFM just can't handle the vibration. Hope our experience may help.

Had this happen to me this morning after filling up at the gas station......the first thing that happened after filling it up----
3 minutes later acceleration was interrupted with engine sputtering, and then the dash lit up with the engine lite, VSC, and trac off...I immediately pulled over and tightened the gas cap......no dice...same issue. I get her home and try once again with the gas cap ...again no dice.
I was on a time constraint and just grabbed my keys to my accord and got on the road,...I cant take a look at it til tomorrow...But seems funny how this is a common issue,..my 2005 is all stock and has 122,000 miles on it,...all I've done is replaced the belts and pads.

Ive owned mine since I drove it out of the lot in 2006 and its pretty much solid.
Ive encountered this issue about 3 times so far, one of my testimonies is actually on this thread I posted a few years ago.
Anyhow, after owning this car for some time now, you tend to know all the common problems so well and fixing them on your own.
- So the first culprit on the dreaded Trac/Vsc/Abs lights is probably the Cam Oil Control Valve (OCV) aka the Cam Actuator.
Ive had to buy this Twice now from the dealers as the Valve/Actuator would stick, and although I tried to reclean and oil the mechanism, somehow areas inside the valve that is not reachable seems to be gummed up and sticking. In 2010 Toyota made a revised OCV (appearantly) to deal with this issue. I havent had a problem ever since.
- The next common culprit is the MAF sensor, the harness and the vaccum tubes. Weather it may be a stock or Cold Air Intake that you are using, Ive found the dreaded lights will come on if the harness isnt connected properly, wires are damaged to the harness, dirty pins or corrosion, bad MAF sensor, Vaccum Tubes arent fitted on properly or not on at all. So keep that area very clean.
- Another common culprit is the Charcoal canister, when people fill their gas tank up, people dont stop after the first click that halts the pump from filling more gas. Instead people continue to pump until gas starts overflowing a little bit. I understand if people want to round off the dollar but to over-do it is another thing. What happends is the Charcoal Canister starts to fill up, when that happends the process of the recycled fumes and so forth cannot operate, tripping out the sensors and turning the lights on. This can also damage the Canister as well.
The not so common culrits are: the Cam Gear itself moves out of place so much that the timing gets out of wack and will throw codes off like crazy. expect your dreaded lights to show up.
Air filter gets so unbelievably clogged that the Maf sensor says: I CANT BREATH , CODES CODES lol! Expect the dreaded lights to show up there too. Coil on plug pack might malfunction, throwing off the timing, making the computer trying its best to work in limp mode, which you will also see the dreaded lights.
The o2 sensor is somewhat hit and miss, as although it helps with the grand scheme of Air/Fuel mixture, it can sometimes be working half way and you will not be getting no codes.
I have been told by a few of my Toyota mechanic buddies that a 5w/20 oil is better for the older 1nzfe engines, being the Cam Oil Control Valve/Actuator can flush out and recirculate oil much better. There is an area that appearantly gums up and it is hard to get at, hence the sticking phenomenon. The appearant revised version of this Cam Oil Control Valve (cam Actuator) has resolved this issue!
Take care

I got the CEL and the others today (VSC, Trac Off), I was just starting to develop
a rough idle and loss of power.
I went to an Autozone and they read my computer and I got the "Misfire on #3 cylinder"
Almost ashamed to say..I have had this car since new, have about 170,000 on it and have never changed the plugs. I put in a new set of plugs and the misfire went away but the engine lights did not, I pulled the fuse to reset them and, so far, all is back to normal. FYI the old plugs, burned down to the insulator were running an effective gap of .085 and I just returned from a 1200 mile highway trip, running 80 plus MPH with no issues (until today)

xBox almost got sold
My 2006 xB had been running a little rough and loud lately, but I thought it was the transmission. I didn't get the Check Engine/Trac/VSC lights until yesterday. I started my car, it kind of hesitated and shook and then sure enough these lights popped up. I guess it had to get bad enough for the sensor to detect.
I went to Autozone and their gauge detected a P0303 (cylinder misfire)code. I swapped coil packs 3/4 and the gauge then detected P0301/02/03/04 code so I knew the swap didn't solve anything. In the parking lot I put in new NGK spark plugs to replace the expensive iridiums I installed last year. I disconnected/reconnected the battery and all the codes went away and the xB sounds normal again.
A couple of notes:
1. When I pulled the used iridiums out they were gapped around .50, way more than the .44 when I installed them last year.
2. I gapped the new NGK's at .44 per Autozone's recommendation.
3. Lesson learned. From now on stick with the basics, especially on a ten year old car.

1st Gen - 2005 xB
Ok just got the xB back.
Only code they got was: P0012
Something to do with the camshaft (so similar to someone who posted in here earlier)
I asked them, what if it happens again since everything they checked seemed to be fine? Advisor was like, well just bring it back....well duh?
Ah well, she drives great still so until it happens again....

Had the same error code, but car runs like new. Anybody coming across this, you may need a new gas cap. I noticed after fill up that the lights would come off momentarily. So it appears there was a leak. I've been filling up the gas tank to the brim, so that may have caused the leak.

Or...
How I spent my 4th of July weekend Saturday...
on my back,
under the car (on ramps),
removing and replacing the Charcoal Canister with a new one from AutoZone.
I was so proud of that accomplishment (about 4 hours of fiddling with picks and hose connectors) that I had my wife take pictures of me posing next to the car holding the new part prior to installation.
