ma4220 Posted August 20, 2008 Share Posted August 20, 2008 I have a 2003 Lexus RX300 and the VSC, Traction control, and check engine light have come on. It has been on for about 2 months. I tried putting a new gas cap on but the lights haven't gone off yet. Can someone help me out on this? Quote Link to comment Share on other sites More sharing options...
smyrnagc Posted August 20, 2008 Share Posted August 20, 2008 Welcome to the VSC/Trac/CEL club. Same thing happened to me...and to many others. One quick question before you go to the threads that I listed below. Did you just have your oil changed? A very common problem for these symptoms is when a technician checks your air filter and opens up the top of the air filter canister it will pull the small vacuum tube off of the right hand, bottom side and this will cause these readings. This was what happened to my 2002 RX 300. I also had a bad gas cap and replaced it for $7 and the check engine light went out. Once the tube was reconnected and the new gas cap then the next problem was clearing the codes. Anyway...Read these two threads that I posted and see what I went through and how I corrected it. Read this one first: http://us.lexusownersclub.com/forums/index...hl=VSC/Trac/CEL Then this one: http://us.lexusownersclub.com/forums/index...hl=VSC/Trac/CEL Good luck and email me if you have any questions.

echo2400 Posted August 21, 2008 Share Posted August 21, 2008 My VSC & CHECK ENGINE lights came on after topping off the gas last month. I took off the battery cable and turned on lights, two minutes later I put the cable back on and it fixed it. A lot of people replaced the oxygen sensor. Some on Avalons had to replace all 3 before they went off. PepBoys or AutoZone will put it on the computer for free. Good luck. Quote Link to comment Share on other sites More sharing options...
the_ian_crowd Posted January 12, 2009 Share Posted January 12, 2009 Thanks for the help! The hose behind the air filter of my 2002 RX 300 was disconnected apparently during an oil change. Quote Link to comment Share on other sites More sharing options...
Monnone Posted June 15, 2009 Share Posted June 15, 2009 Same thing just happened to me. I had to have the transmission rebuilt. Sucks I know but I understand that is common on the RX too. Anyway, the hose was indeed disconnected. I reconnected it, reset the battery - no lights. So we'll see if a few days if they come back on. I thought I'd post a few pics as this seems to be a common problem: Brian 1 Quote Link to comment Share on other sites More sharing options...

dealmonster1169 Posted September 29, 2009 Share Posted September 29, 2009 I have a 2003 Lexus RX300 and the VSC, Traction control, and check engine light have come on. It has been on for about 2 months. I tried putting a new gas cap on but the lights haven't gone off yet. Can someone help me out on this? I have been having the same problem. Along with this, it feels like the ABS brakes are activating when I begin to move from a stop. Did you expereince this? I see your post was from a year ago, so wondering if you did find a solution that you can share. Thanks! Quote Link to comment Share on other sites More sharing options...
ma4220 Posted October 13, 2009 Author Share Posted October 13, 2009 Mine ended up being the rear O2 sensor. I replaced that and that took off the check engine light but the vsc and trac control light came back on. I have heard you have to go into the computer and reset them. Haven't had time to do it yet though. Quote Link to comment Share on other sites More sharing options...
saz1277 Posted June 5, 2011 Share Posted June 5, 2011 I have been having the same problem. Along with this, it feels like the ABS brakes are activating when I begin to move from a stop. Did you expereince this? I see your post was from a year ago, so wondering if you did find a solution that you can share. Thanks! Hi. I'm curious to see if you ever found out the problem or solution to your ABS activating when accelerating from a stop? I've been having a similar problem for quite a while now with my 2001 Lexus RX300, and no shop, including the dealership, has been able to figure it out. From a stop, I get an intermittent shudder before the gas engages, and the traction control light comes on for a moment. No other lights, etc... Thanks for your time!

Instead of having the console light up like a Christmas Tree, and confusing the mechanics, how you solved it is HOW I SOLVED IT. SIMPLE. 10 MINUTE JOB. Thank you so much to THIS FORUM and to Brian Monnone......Finally the quote showed up below, and I think it took time to show up as I am posting since it had pictures in it. The KEY is the pictures.
