#277 of 298 Multiple warning lights
May 19, 2009 (4:38 pm)
Has anyone experienced several malfunction/warning lights coming on at the same time, without any prior event that might have caused this (such as a panic stop, etc.)? I started my 2005 Avalon one morning last week, after it sat unused overnight, and found that the "check engine", "VSC" and traction control warning lights all illuminated. The same warning lights continue to come on since then and I have since discovered that the adaptive cruise control is also not working ("E3" code displays when attempting to engage cruise control). Car is being serviced today, by dealer - technician seems clueless at this point about what would cause this and wants to charge me for the electronics diagnosis which they claim is not covered under the Toyota extended warranty (7 years, 100K miles) I have. Anyone else have this happen to their car?

Can't tell you what is wrong with your car.... however I can tell you that if a condition arises that triggers the check engine light the VSC/TRAC system is disabled and turns those lights on as well. Since the laser cruise uses those systems it probably is disabled as well.
As for the charge to diagnose, isn't this deducted from the bill if you choose to have it fixed?

Could be something as simple as a gas filler cap not fully tightened or someone removed the cap with filling the tank.

Thank you tjc78 and also wwest for your help (Responses #278 & 279). My problem turned out to be a defective gas cap seal. They replaced the cap and everything seems OK now. I gave the service rep a copy of your response (#278) and asked why the dealer's technician didn't know what you knew: namely, that all these other systems (VSC, Trac, laser cruise) would be affected and display warning lights/error codes if the check engine warning was activated. Didn't really get an answer to that, altho he said that their service manuals don't mention that (!) - so they thanked me for showing them your reply and said they would share it with the service technician who worked on my car. Sounds like you helped not only me, but my dealership's service department too! So thanks again!

I have a 2002 Avalon and we've owned it for several years now. Last year we experienced the engine not idling like it should or at all, would stall at stop signe and traffic lights too. Anyways, I took it to a friend and he blasted some SeaFoam through the intake and since then the car has been running like new until recently. The check engine light and the VSC lights came on as well, just like last time. What could be causing this and how can I fix it without a really big expense?

Had exact same problem about a month ago with idling issues on an '02 Camry 130k miles. I had to have car towed because I could not keep it running. No warning lights however. Turns out the idling valve needed to be cleaned out - My mechanic found issue quickly cost $100. Runs like new again with no problems since. They only real issue that I have had on the car for 6 years was this.

The idle air flow bypass port, bypassing the throttle plate, is fairly small and easily plugged up if the intake filter is not changed out often enough, or if someone (read: IDIOT..!!) switches in a "free-flow" K&N instead of staying with OEM or equivalent air intake filters.
Newer DBW systems do not use/need the bypass port so the only real damage a K&N can do is contamination of the MAF/IAT sensors.

Sounds like an IAC (search in this forum and Google for it with Camry's as well) issue at least, there are posts in cyberspace with descriptions for DIY'ers.
Once cleaned, you could try to reset the error lights, but if they come back you may have to check/clean and or replace your MAF and oxygen sensors.
#285 of 298 Air Bag light issue
Jun 07, 2009 (8:47 am)
Hello, thanks for everybody's enlightening responses.
I have a quick question:
I have an '03 Avalon, 59,000K, upto date on maintence. Over the last few months, the airbag light blinks. It will only blink for a few days and not light up again for a 1-3 wks, followed by a repeat of this cycle.
It is hard to arrange my schedule and sched a check up while the light is on during that short period of time.
1. Can this issue be trouble shoot while the light is off?
2. Given the obvious importance of an airbag, should I only go to a dealer?
3. Any suggestions on Toyota recall websites?
