Is there an 02 sensor check that can be performed regardless of a check engine light? My car is in for the alignment fix right now, I wonder if I should have them check that out as well for preventative maintenance?
Yes! they replaced the O2 sensor it was cracked it fixed the problem. I just changed the oil on my own because I just got paranoid. Alot of IS250 owners with gas in the oil and they had some of the same warning lights as I. But you have the same warning lights like I had,its probably just the O2 sensor but you'll never know. When you take it in have them check the oil.
Most performance mods need a watch and timed course to demonstrate actual improvement. Few deliver the advertised claims. Many are actually worse than stock. The best performance mods are made to the driver.

I saw that post with the TSB and while my VIN does fall into the range of those indicated, I am unaware what codes are being thrown so at this point I can't say if this is definitely the problem. I figured I would post anyway to a) indicate another person has experienced a similar problem and b) provide the info that I get from the dealer when it is fixed.
I am one of those lucky guy, I guess, it happened to my IS250 this morning after starting my car for like 5 seconds..... Just got to work and read all the comment with this thread. Probably go check out my gas cap first, then see if that is the problem. =(
Have the same issue, 2006 IS250 6 months old, 7000 miles, I got the check engine light 3 weeks back and that was maybe leaving the cap loose issue as the service center said to see for a few days, it went out the next day. Now just yesterday had the same issue agan only thi time the dealorship wanted to check the issue. Seems nothing is wrong and they resetted the light. Said there is a TSB out and lexus is working on the issue of a software tcu update.
Was told if it happens again than they would need to look further.
I just got my 350 back for a CEL and check VSC warning. After them keeping my car for 3 days, they came back and told me that I had a cracked gas cap that was causing the problem. They replaced the cap and the lights went out.

Add me to the list . The check vsc light came on along with the skid warning(explanation point light), and the check engine. I have a 2006 250awd with 6600 miles. This is the **** that bothers you with high tech computer cars. You know you can't fix it yourself, so you need to bring it to the service so they can plug it in. I will let you guys know what they tell me.
It did happen when my gas was very low. I filled up, screwed on the cap tight, and the light is still on.
I almost want to just disconnect the battery to see if the light does not return. I hope lexus will solve the problem.
After getting my car back from service, I'm happy that the CEL/check VSC lights are out, but it kinda makes me wonder.
So far we've heard reasons like, faulty O2 sensors, gas caps, etc, which may all be valid reasons, my I'm just wondering how any of this is related to a problem related to the VSC system?? I could see the CEL coming on for the O2 sensor and even the gas cap, but the VSC?? It doesn't compute. Next thing you know they're gonna tell us that the ABS isn't working because I'm low on washer fluid.
Maybe it's just me.

You are right, what do these problems have to do with the VSC system? Damn these computers!!!!!

I have the same 3 lights comming on as everyone else. I brought it to one of the Techs i know at my Lexus who is a friend of a frend. He said the Check engine light is connected to the VSC, so when ever the check engine light comes on it shuts the VSC off and the light will come on. He did not know what the problem was but said it was probably becuase of my Fujita intake. He said the engine is probably getting too much air and the computer doesnt recognise it or something like that. He reset my computer and the lights went off. He told me to take it back if they come back on. Well, a half hour later after going into a store i turn my car on and there you go, all 3 lights on again. I am going to try and bring it back tomorrow and make him check the gas cap and O2 sensor. The light has been going on and off for a few weeks now.
Does anyone that is haveing these lights come on also have an aftermarket intake?

Well, I just went out to check a few things with the car. I smelled the oil on the dipstick, and I thought it smelled like gas . I checked it again, and said yeah, I think it does.
I then went over to the S2000 to smell its mobil 1 oil. No bad gas smell there(great car )
I had the oil changed on the lexus at 5k miles. This has me a little worried. Gas in the engine oil could had very bad effects on the ability on the oil to lubricate the engine. I will call lexus first thing tomorrow, and let you guys know what I find out.
Does anyone know if gas is less dense than mineral car oil? I wonder this because if it is you could smell it on the dipstick because the stick would enter at the top of the gas/oil mixture. If gas is in the engine, it should float to the top and be detectable by its smell.
They tell you that because it is the most common cause of a CEL. It may still come back, and personally, I wouldn't take that route. I'd ask to see the code so I can know if it is an evap emissions fault or something else. They just had you do that because it's simple, quick, and common.
Connecting a scan tool takes all of about a minute total to read a set code, and even a cheap scan tool will be able to tell you if it's the evap system.

Anyone seen or heard of a PO200 or P0200? It's the code I got on my IS350. Apparently it's a faulty fuel injector/cylinder? I think they said the cylinder is not getting enough oxygen?
