- The Check engine light with the TRAC OFF and VSC lights would not go off with a new gas cap, nor unplugging the negative terminal from the battery. So after purchasing a few tools and a Mass airflow sensor with both the Up and Down stream O2 Sensors, the problem was resolved and the GA emissions passed with no issues. Here's the links for the tools and sensors

I've researched this for a few yrs. Ever since Toyota worked on my mother's 06 RX330 this has been a problem. Plus dumped over $700 into it trying to resolve. It's also a part of 04-05 recall that they refuse to honor in the 06.
Ty for the video!
Ha! Mine is a 2004 so I should have had them fix it. Oh well, I figured it out and now I know more!
If you have check engine light and vsc light on, please check your tires pressure. I have two Lexus with the same problem when tire pressure overinflated. Tire pressure is located on driver side door. I finally figured this out. Nothing on CZcams. Hope this helps anyone!!!
Never would have thought of that one thanks!!!
Thanks for the nice. My tires are set at 45 PSI. I will check in when I get back home. The VSC light and check engine light came on when I stopped real hard in traffic.
Great video .. I learned it can do by my own
Thanks you
great video, same lights have stayed on as well. was told it was a cat replacement. will try this! specific brand of 02 sensor you used or recommend? always can ask the associates in store but just to have something to off of instead of asking google. lol thanks in advance
I just bought them off Amazon, half the price of the auto parts store and worked perfectly. Make sure you get one for the pre cat and post cat as they have very different connection points.
I have the same problem with my car but my cruise control doesn’t work, did yours work at the time with the those light on
Didn't check to see if cruse worked during the lights but they were O2 sensors that were the cause so can't see them being linked together. But I've done a bunch of research and some people said that it was their gas cap that wasn't holding a seal as well as other said it was due to a vacuum leak in the main air intake. Some needed to get to the mass air flow sensor and clean it and they put it back together and it was fine. However, troubleshooting 101 sometimes requires us to simply take it apart and put it back together. By doing that, the loose bolt or screw that looks fine at a glance ends up being the problem gets solved simply by taking it off completely then knowingly putting it back with intention. Let me know how it works out
I have same 2004 rx330, I don’t have any lights on but when I scan using BlueDrive it keeps showing Oxygen Censor scan not complete , but Ixygen Sensor Heat scan is complete, do you think I need to replace the Oxygen sensor like you did?
It's very hard to say what the issues are for sure at this age. I still drive my lexus rx330 everyday. Something new pops up once in a while but after I did the o2 sensors a ton of issues with the dash lights went away and the car seemed to have a tiny bit more power, which if the sensors were bad, would cause fuel air issues. Small other things to look out for is the gas cap. You would think it would make the computer go nuts but if yours is leaking air it will throw a code or 2. So in the end, it's a fairly easy repair and cheap parts so if you have high mileage and never replaced them, I'd do it. Also I'd replace the mass air flow unit as well. Let me know what you find
Can you show the link for the tools and the sensors you purchased. I have the same lights in and problem.
I would but the ones I bought since this video aren't the same. I bought them on Amazon so just look up your car and make sure it fits your vehicle. If we could speak on the phone I'd be happy to help but what if do is go to a local car parts store and tell them what you need O2 sensors and they will tell you the parts. Then, go to Amazon and look them up.
I need your help
There are actually 4 of the sensors. Two up stream (pre-cat) and 2 post. I'm going to do like you and replace the two easy ones, yes easy ones first.
I didn't know that, thanks!
When all them lights turned on on my 06rx330, i had to replaced my throttle body because i lost a siganal from gas pedal to throttle body.. since the tps is built into the throttle body. Solved the problem.. but i still noticed from time to time my abs. Vsc, trac off and that tire pressure light flashing would come on. But no check engine light tho. Do you Have any suggestion what to look into fixing it?
It's funny but I think those lights come on for a million reasons. Basically I think when anything goes wrong, those lights all turn on. So many people have posted they had completely different issues but those lights came on just the same. 1st time for me was a leaking gas cap.
Yeah, but ever since inreplaced my throttle body it had only turned on once after a yr. It was break switch. But when i turned the key off and turned it back on it gone and haven’t turn on since then till now. Knock on wood. Lol
@tengzturiagaiii3185 here's hoping
P0171/P0174 system lean, actually is you have a vacumm leak in the emission system. Make sure the vacumm hose is connected correctly their is a diagram on the hood. I fix my P0171/P0174 problem. O2 sensor will give you a specific code just for that.
Good to know!
I have 2005 330rx lexus check light on code p0016 and p0018 and i take to 3 shops and i cant get fix
Do you have the bluedriver? You can get them on Amazon for 100. Works on both iPhone and android. Reads the deep codes and even shows where to get the parts and links to support sites. Saved me thousands
Thought you can access these sensors from the bottom not the top.
I guess that depends if you're jacking the car up in a home garage vs. having access to a lift. But no matter what, it's gonna be painful process
My P0300, P0301, P0305- miss fire, P0346- camshaft position sensor. I have no idea put I will try and do myself. 2004 Lexus Rx330
Im havin the same issue... i replace the catalytic converter and vsr n trac light still on... i order o2 sensors now i need to get them put on
It said I needed to replace the cat as well but after putting in the 02 sensors the lights and messages went away.
I had got the o2 sensor but a shop told me I didn't needed them I guess cause I'm a lady n I replace the cat 1st n then I seen for myself that the o2 was definitely bad... are you in atl area

How does the VSC in the ABS button and the track off Hass to do with the O2 sensors😂😂😂😂
What does a joke have to do with a laugh?
