#46 of 73 VSC / Engine Light
Feb 09, 2008 (8:06 pm)
My 2002 Lexus RX300 had the VSC and check engine light come on today. I did just get the oil changed about 500 miles ago, so I checked the hose behind the air filter and sure enough, it was disconnected. I reconnected it, then the lights didn't clear so I had to disconnect my battery to clear them. I hope it stays cleared now. I did notice my clamp that holds the hose on is not very secure, so may need to get a new one. Thanks for the tips, WAY better than getting charged at the dealer for something so easy.
#47 of 73 Help engine light and fuse question
Mar 27, 2008 (3:21 pm)
Hello I have a RX300 the engine light keeps coming on and nothing is wrong with the car. I will check the hose behind the airfilter, as suggested in a ealier blog thanks to whom ever. I also have a dummy light for my "lights" I have checked al my light even brights. All good except for the(2) yellow light in the front of my car on the front quater pannels. I am thinking it's a fuse is their any easy way to find out which fuse it might be, I have looked at the owners manuel and find it hard to locate? Thanks

Our check/VSC light came on a couple of weeks ago. Not the gas cap, not loose hoses. Free AutoZone diagnostic reveals: 02 sensor! Fused to the manifold, I was told it happens to about 1 in 50 RX. Expensive little repair as they have to replace the sensor and the manifold... There goes the old tax rebate check!

You know I really wish people joined the forums which already have hundreds of your fellow car-make owners who could save people thousands...Just think about it, WHY would they fuse the o2 sensor to the manifold? All the o2 sensors which I've seen in my life were ALL threaded. Its like saying that if you have a cut on your hand, the doctor needs to replace your entire arm. Nothing against you, I am just trying to save you money in the future, when I bet you could have found a much better use for the money from the tax return...
Do not trust the STEALERSHIPS!! I can't stress that enough .
#50 of 73 VSC & Check Engine Light - IGNORE
Mar 24, 2010 (7:08 am)
Why have manifold sensor replaced? Why not ignore? VSC has nothing to do with the engine. The check engine light is probably associated to Manifold sensor.
Not sure just voicing an opinion

"..Fused to manifold.."
Get thee to a welding shop and have them use a gas cutting torch to HEAT the manifold while avoiding heating the O2 sensor, then remove the "fused" sensor.

I believe this is a COMMON problem with toyota cars. I had a 98 camry several years ago. The check engine light went on after the first month I purchased the car. I remembered that I went to dealer at least 4 times for repairing that the same problems during the first 4 years of my ownership. After then, it kept on and off and I just ignored it. It was really bothering. But I found that it was ok if you ignore it. Four of my friends had the same problems with their toyota cars (camry or RAV 4), too! For this reason, I did not buy camry any more.
#53 of 73 Toyota O2 sensor

I had corolla 2000 model. my CEL light was on abt 40K miles for the same O2 sensor.. drove till 95K without repairing.. thought emission test will fail.. but took battery off to turn CEL off and went for emission test and it passed.
Now I bought 2007 highlander.. I have 45K miles on it.. same problem.. P031.. O2 sensor.. shopping for cheaper replacement.. if I don't get it.. wait till emission test fails..

If the O2 sensor fails by 40,000, that's way too early. Could it have been the fuel in your area?
Do you use any cleaning product for the system?
It was warranteed at least until 70,000 for emission-related items, wasn't it (U.S. vehicles)? Why not have the EFI cleaned or the defective part replaced?
I wouldn't use a cheaper third-party sensor. You can see the difference when you have both side-by-side.
Other RX300's tend to need cleaning of MAF sensor and the idle servo (really easy DIY and lots of tips using "search" on this and other sites) long before O2, but those have different codes.
I hope the info helps. I'm really surprised your OEM O2 sensor didn't last very long, and it happened twice.

Thanks a lot for sharing this information! I fixed it by simply reconnected the hose. Got rid of engine check light after disconnected battery for 15 minutes and.
