Some months ago I posted a problem I had with my check engine light coming on. With it also came the VSC TRAC and VSC OFF lights. I thought it was cleared up but it's becoming a real problem so I'm going to take it in the the dealer.

To rehash: for unknown reasons, these lights went on. Had them checked at Autozone with no real results. Guy said it could be a lot of things. Code P0446 = Evaporative Emmission Control System Vent Control Circuit Malfunction. I had it cleared, came back on a couple of weeks later. Reset the ECU to clear it and over a month later it came back on. Tried one last time just because I didn't want to look at the lights and 2 weeks later it's back. There are no noticable differences in performance as far as I can tell and there are no mysterious noises or smells.

I'm going to take it in, but I am concerned about getting jerked around since I've got absolutely no clue about this sort of problem. My original thought is that this might be one of those little things that they do to make you go in for service. I had the 36k done but not the 45k. Not sure about that, just an idea.

Do they charge to check it out? What should I expect? Any help would be greatly appreciated.

A case for extended warranty here.

Got any warranty left? If you do I would imagine it would be covered under that. If not, I would ask all my questions up front about what it is going to cost and not get nailed with a big bill after the fact. Make sure they call you with what they find out and what they recommend doing BEFORE they go ahead and do it. You'll be richer for it later!

This code usually means hat there is a pressure leak somewhere in the evaporative system on the car. There are several reasons for this which include: gas cap is leaking or faulty, the fuel filler pipe (it may be venting some pressure due to a clamp being loose), all the Evap Emission hoses could potentially have a leak and finally the vapor canister could have a stuck valve if there is one.

Thanks for the assistance guys. Waskilly - no warranty left, I just hit 50k yesterday. Besides that I'm sure they would try and void it if it was at all possible due to my modded intake.

MTL - is there any way for me to check any of that myself or am I just better off having the dealer look at it and trust them to not screw me?

Just for an update, I took it to the dealer to make an appointment so no actual diagnosis yet. The tech guy said usually with 4Runners it is the O2 (I hope not) or the MAF. My friend's O2 went bad on his '00 Taco, so I suppose I believe it. Just in case I cleaned the MAF, air filter and throttle body today. Not sure if I should reset the ECU or not because the appt. is next friday and it needs to be on for them to diagnose it. I'll give details for what I find out.

Hey guys, my mom has a 2001 highlander, the VSC light and the check engine light went on yesterday and stays on all the time now... Could it be the O2 sensor too? We should have just gotten her a 4runner since she drives in broccoli fields everyday... her muffler has so many dents in it....

Thanks!

Just in case anyone was following this thread, I went to my appointment at the dealer today and it turns out the problem was along the lines of what MTL suggested. The VSV valve was stuck open. Replacement part $44, labor $150. :pat: But what are ya gonna do? I have no idea what a VSV valve is or where it's located so I couldn't very well fix it myself.

Wow... on the highlander, it was a hose that fell off, I actually found it and was looking for where it fits, but my mother was in a hurry to go out and couldnt wait for me to figure it out, so she spent $75 at the dealership to get it fixed the next day......
