I have searched and not found. So I'm asking you guys. We are currently on a trip to see family 1500+ miles from home. I got in my 4runner this morning and the check engine light was on. Scanguage II says 2 codes. Both P0000 and the "VSC Off" light was blinking and traction control light was on. I cleared the codes and everything looks good. Any suggestions on what (if any) problems this might be? It is about 30-40 degrees cooler than we're used to. I also put premium fuel in during higher elevations, 10,000+ feet at times.
Error code P0000

That sounds like an issue with the Scangauge. From what I googled it looked like its a software error that creates a P0000, which seems too be the Scangauge's way of saying "no DTCs found" but if you upgrade to the newest version you should be good.
What year is your 4Runner? Because the lights do tend to blink when it is communicating on the CAN bus searching for codes. You could have also reset your ZPC if it was an '03 or '04 because those models were very finicky about that (I somehow manage to reset mine almost every other time I check for codes).

My point is, as far as I know a P0000 does not exist as an OBDII Code. So either the ScanGauge cannot read the actual code, or it is producing a glitch (which by what I Googled showed that the Scangauge does have an issue with creating this code) of some sort.

thanks for clearing this mystery for me. I just bought a mini vci tool for $25. scanned my 03 this saturday. drove off and immediatly it popped vsc and tracs.
went back into techstream and poked around to find where was ZPC reset and found out the hard way(trial and error) that i needed to do this each and every time i scanned the truck!

You don't need to run premium fuel at higher elevations. Engines don't need higher octane at higher elevations, its actually the opposite. I live at 8000ft elevation and the gas here is 85, 87, and 89 or 91 for premium depending on brand. My '03 V8 runs best on 85 up here.
Now I see what you are saying. I cleared the code without any issues arising. I know the Scanguage will also mess with the VSC off light. It did to mine. Thank you for clearing this up.
I thought I read somewhere that at higher elevations it was recommended to run premium, but now that you mention it I realized that it is opposite. As a side note my MPG's climbed from 18 (hwy avg) to 22 Once I got to New Mexico. They stayed that way all the way back to Texas too. I only ran premium through one tank.
Thanks guys for your help.
*update*
My lights came on again this morning. I pulled into the auto parts store and they were able to read 10 codes all referring to an evaporative leak in the emissions system. This confirms that the ScanguageII doesn't read all codes, mine has version 3.5, maybe an update would fix it. I have a new gas cap on order to fix the codes.

No it reads codes just fine...you just have a bad unit.
That's why I am going to update it.
For anyone still reading this thread that wants an update:
The light came on again this morning.
I have installed an OEM from the Toyota dealer and I made sure that it goes past 5 clicks. It feels much tighter that the old one but the light still comes on.
In my searching I have found that a number of people have this problem when the weather turns cold. I'm not sure that is a factor but I noticed the trend.
For many people a new gas cap fixes the problem. So far this is not the case for me. Since the new gas cap I have had the lights twice. I cleared them both times with my SCII Ver 3.15 (I know I said 3.5 earlier, but it is 3.15). I would like the weather to warm up some to see if that makes a difference but I also don't want to fight this battle every time the weather cools off.
I will update again when I find the solution.

so you are saying that auto store came up with 10 codes related to evap. leak in emissions system, so you replaced gas cap & lights still came on, right? maybe its me but i would think theres a bigger or different problem, & take it to a shop right away instead of constantly resetting it. a new cap may work for some but its not a cure all. i believe blackworksinc recently posted about this- http://www.toyota-4runner.org/4th-gen-t4rs/151487-check-engine-trac-vsc-read-me.html

The temperature here varies from +35 to -35 degrees Celcius and I've never had any engine codes associated with it.

Do this, open the hood with the truck running in a quiet place. With the hood open, listen for a sucking hissing sound coming from the drivers side is the engine. Trying to get you to find a vacuum leak. Could be a rotten hose.
Touch the rubber hoses, tug, push and pull and see if any of them make a noise. Easiest way to see if you have a busted line.

This one came up in my searches. Excellent post. I followed it with obvious hopes of the gas cap problem.
I'm going to try this next. Unfortunately I will be out of town for the next 2 weeks in the wife's car and won't be able to try this until Jan 1. I will update then.
I want to continue this thread to document my progress. I have only been able to find a few related issues but so far they all stop at gas cap or they just stop completely. Thank you for your help so far.

So I got under the hood today. I couldn't hear any hissing from the driver's side of the engine bay while running. I got the codes. Turns out that the original 10 codes are only 5 repeated. They are as follows:
P2401
P2402
P2419
P043e
P043f
All related to evaporative emissions. O'reilly's printed out the common problems associated with these codes on 2008 4runners (not too sure the reliability of this).
First - the charcoal canister.
Second - gas cap, already confirmed that this is not the problem.
Third - the evap canister, I thought this was the same thing as the charcoal canister but I guess there is a difference.
Other forums I've read on the evap canisters end with $1200 quotes from the dealership. I bought a repair manual and I intend on fixing it myself. Any thoughts or comments are appreciated.

i circled the hoses i was talking about. i found a similar codes on my friends lexus sc430 in this area. hose was disconnected a little bit. in your case it may be cracked or busted. worth a check. squeeze it to see.

smoke testing of the evap system would find your leak pretty fast (if that's the issue). May also be a VSV fault if these still have them.
their "most common issues" should be taken with a very fine grain of salt. Those are big conclusions to jump to, and they want to sell you parts of course. (except the fuel cap is common on anything with evap large and small leak codes)

I thought the same thing. Funny thing is they don't sell the EVAP canister nor charcoal canister.
