- What to try first on your Lexus when these lights come on. This cannot diagnose your issue and is to be used at your own discretion.
I love my GX and thanks to your videos I’ve been able to keep it rolling past 200k miles
Got a 04 GX470 same codes popped up. Checked the gas cap it was original and dirty, rubber gasket was hard and brittle. Bought new one off E-Bay, installed. Lights went out next time driving to work, perfect!!! Thanks much!
That thing makes a difference! Lot of times it’s just loose
Replaced the gas cap and drove the car for a few commutes. The lights went off. Hope that they will not come back soon. Thank you for the pointers!
What codes did you have?
You made my month! with this video.
Pull the codes hopefully it’s an evap code and simple fix 😌
Just the info I needed! Was driving the GX yesterday and all the mentioned lights came on all at once! Gonna try the gas cap recs and take it from there......hopefully that’s the fix 👍🏼
Thanks
Make sure it’s just an evap code, pull the codes first before the cap
@@crutchfieldautomotive7936 will do. Thanks again
@@crutchfieldautomotive7936 : So went out and checked the cap last night and realized it was not even turned past one click! I must have been pretty absent minded the last time I fueled up and just barely put the cap on. I’m guessing that’s the culprit. I’ll be more mindful of this going forward. Thanks
Gas cap works like 1/3 of the time.
Have an 05. Same lights on like the thumbnail. Pulled a P0340 and P0345. These point to camshaft sensor but somehow connected to the evap thus replacing the gas cap? All this after jump starting the truck.
No both of those point to the same cam sensor, inspect wires to it, pull it and inspect for metal or extra sludge
Do you know how to use a multimeter very well?
Not experienced but willing to learn. Did I mention I pulled these codes after jump starting the truck? Also had a TB service about 2000 miles ago.
@boymata ok I would start with the electrical issue first if it be the battery or alternator
@boymata then check codes again after clearing and inspecting
Thank you sir.
Love all the support for this vehicle… thank you
These lights just came on today… I just picked this 2007 gx with 82k
Run the codes and I will do my best to help figure out what they are for
@@crutchfieldautomotive7936 just like you said I got the evap code P0456 and also got a C1201 code… brake boost sensor
2007 GX470 260K -- 3 dash light indicators on: VSC TRAC; VSC OFF; Car with squiggly lines symbol. No Check Engine Light. ONLY Codes TPMS all four (C21nn) , and air bags circuit fault (B0136, B1148). Driver front break caliper is dragging on disk (disk gets hot). Mechanic (not Toyota trained) thought caliper might be rusted - needs cleaned and greased. So, is PCM/ESC trowing light due to caliper binding or is caliper binding due to PCM issue. Again, no other codes coming up for PCM/ECM. Center diff engages/disengages. Gas cap closed. How to diagnose?
That’s one I haven’t seen. Is there a Toyota tech anywhere near? The airbag fault can be as small as the wire under the seat. With no check engine light the most common issues I’ve seen is the ECU-B fuse blown, under the hood. I know that seems totally unrelated, and very well may be, but it’s worth a look at least
@@crutchfieldautomotive7936 thanks. I check it out
Let me know what ya find please
Dash lights cleared themselves after driving about 80 miles and restarting engine. Didn’t mention that they had previously also installed a new battery which cleared codes. Have not checked the front caliper that’s dragging to see if it’s rusted and needs grease, or a system problem. Re:airbags The vehicle had been in an accident on passenger side (T-bone) and all airbags deployed and were subsequently replaced. My guess is fault is related to that history. Something funny with driver side lights - 3 bulbs out. Owner is asking 4500$ - probably will offer half that to start.
Pretty cheap if it’s functioning correctly otherwise
Thank you
every GX owner probably experienced this lol durable suv but dramatic. I just replaced my gas cap.
I replaced my gas cap and battery and still won’t go away
Did you pull codes?
Thses lights with p0031 code, replace the 02 sensor?
Love this guy
Hi! Thank you for the video! I got all 3 lights like in the video. And the error shows on obd say its P0051. Do you think replacement gas cap will help?
No, that is going to be an oxygen sensor code
SAME! All those lights. Code said a 02 sensor. Replaced gas cap. Only issue I have is when driving, it does NOT have the same take off as it did. It is more reserved on the take off. Like it is holding back. 😞
Have a temperature gun? Infrared or similar?
Your engine is running lean because you didn't replace your O2 sensors.
Mine is because of the long pipe headers on it. Now my code readers will not read the codes. Is it port 5 and 13 that you can connect a paperclip to?
Hey there, nice video. Thanks for making it for us. Quick question, what if the VSC Off and Track off lights comes on while driving? Should I worry in terms of safety?
You do lose traction control function and sometimes ABS function in emergency sliding situations. Beyond that, no. I personally wouldn’t be afraid to drive it, just know those functions aren’t active and it’s going to drive like an older vehicle at that point.
My trio lights just came on. I just ordered a OEM replacement gas cap
Run the code first, make sure it’s a emissions leak
Hello, my 2009 Lexus rx350 vsc light is flashing also my check engine light and traction is on. Last week I tighten the gas cap and all lights went off, but a few days later they came back on. The car shakes when I accelerate, some times it dose that and other times it doesn’t. Auto zone read it and the ignition coil came up and the abs relay. What should I do?
Replace the coil and the relay and should take care of those
Hi, pulled codes P0456 and C1201. Got a oem gas cap and fitment was worse than the one it had. Took out the o-ring from the new and used it with the old cap, lights are still on but will try driving it a bit more to see if they go away. What is the fix for C1201?
1201 is ECM malfunctioning. it could have directly come from the evap code above. Did you disconnect battery to reset or have a scan tool to reset?
@@crutchfieldautomotive7936 No I have not disconnected the battery to reset, I will try that, thanks!
@@crutchfieldautomotive7936 Just wanted to update, I never got around to disconnecting the battery to reset. However, all the lights went off after a bit more driving (it doesn't get driven much), so about 370+ miles total after the switch it seems to be resolved now. Thanks for what you do!
You may need to do the SAIS bypass as well. just did that for mine at 118k miles. first time around, mechanic replaced the cat because he thought that was the problem, came up again just recently. Went and bought the bypass. no codes. i was getting a p1445 or p1442. same lights came on. also heard the the ecm or ecu chip can be faulty in colder weather and set off false positives.
Yes they can definitely need that as well at times, this one was just the cap fortunately 💪🏼 for now anyway 😂
Did the codes ever come back? Did you do the Hewitt bypass? I have those codes specially in the winter. No issues, just the lights that I clean with the scanner.
I got Cat convertor under threshold bank 1 and bank 2, is changing the gas cap going to help with it?
0420 and 0430 codes?
@@crutchfieldautomotive7936 yes
Unfortunately no, 95% you’ll need catalytic converters
checked gas cap, ran a few tanks, still on. replaced gas cap. rand couple of tanks still on. disconnected battery, still on.
Its the most likely cause of a code but you still have to run the codes to know it’s not something besides the evap leak code. Did you have codes pulled and if so, what codes came up?
Can you please tell me where to get the gas cap that you get for the gx470s? I just bought one off of eBay and it's just as loose as the old one.
OEM from the dealer, but did you pull codes? What codes you get?
@@crutchfieldautomotive7936 i did hook up my scanner but i didn't look at the codes i just erased them.
They are back again though now.
It takes no effort at all to remove the gas cap with the old one or the new one. I ordered one from Amazon now that the seller is a Lexus dealer so im hopefull that it is OEM.
Were the codes are for the evap leak?
@@crutchfieldautomotive7936 I didn't even look at the codes at the time.
Gotcha
What about if all those lights come on except for the traction control? (Car with squiggly lines) can I assume it’s a similar problem?
You still need to have codes for either way to know what’s truly wrong that’s just a very common reason on these
Got the codes read and it came back as the speed sensor. Makes sense because the cruise control wasn’t working either. Thanks for the videos I’m a new GX owner and these have been great!
@alexpond6132 nice those aren’t bad to swap either hopefully just the sensor itself
I just got this with my 08 gx470. It’s showing a code p1445. Is it the gas cap?
No, you’ll need to be looking at the secondary air injection system. There are two routes, replace or bypass. Sometimes clearing the code is a fix for a while but it will need attention eventually
Is there a certain amount of miles that you need to drive before the lights goes out? My wife just put gas in yesterday and the lights are on now. I retighten the gas cap She only drove it once since then. Just wondering if there's a specific amount of miles he needs to drive to have the codes clear
The codes aren’t necessarily just the gas cap, can you pull the codes to make sure?
PLEASE HELP! We just had Bilstein 5100 shocks installed and these lights came on immediately after not being able to plug the shocks in. How do I remove these light with my after market shocks? thanks!
All of those came on or just 2?
Because we delete shocks all the time with no lights, you’ll need to pull codes to see what they’re saying and I can help from there
Will run a scan tomorrow. YOUR A LEGEND BTW!
Ha thanks holler back with what you get for codes
The CEL isn’t actually on it’s just the abs vsc trac codes. I ran a scan with my cheap 25$ code scanner and it said no codes. I’m assuming it could be an abs/wheel speed sensor that got roughed up a bit during the shock install?
Any ideas when only VSC Trac, VSC Off, and check engine light on (but traction control light is off)?
Get the codes read and see if it gives you some ABS codes along with anything else
Hey, everything was running fine and dandy until I pulled my battery to change my driver side blinker... when I went to start it up after the project was done I had some noise and some misfires and these lights came on. I will be pulling a code first thing tomorrow with my reader. Any thoughts on what could be going on? Once again, Thanks bud 🤙
After pulling a battery there’s no telling, it shouldn’t have had any bearing on it honestly. Codes will be the most helpful next step
Lol I just got all three codes today, I was expecting something to blow up as I drove to work deeply bothered 😥. Thanks for the video I'll order a replacement gas cap 👍
Pull codes first and make sure it’s an evap code
I changed my gas cap with a Lexus gas cap. The lights went off but came back on again then a couple of days later it went off again. Then I noticed almost every time I hit a bump it comes on then goes off. Any idea what could be causing to come on and off?
Have you run the codes?
@@crutchfieldautomotive7936 Yes I did but can’t remember I know they told me it could be the camshaft sensor. But after reading up on that my vehicle is not showing any symptoms of a bad camshaft sensor.
If it comes back have them read again and let me know what they are
@@crutchfieldautomotive7936 Cool I will. Thanks
@@crutchfieldautomotive7936 Hello sorry it’s been a while. I finally got around to checking the code for my Gx. The first code that popped up is P0345 the second is C1201. What are your thought? If it is the camshaft sensor is it hard to replace?
Thanks 4 the info..
Stay safe
Thanks, will do!
Hi. I have a 2007 GX470 with 290k miles. Lights came on, tried gas cap. Did not work. Pulled codes and got "P1442 Secondary Air Injection System Switching Valve No. 2 Bank No.1 Stuck Closed". I now know what the problem is and how to fix it, which from what I've seen looks like a big pain. My question is, is it safe to continue driving the truck for a while or will it lead to any/more damage to the engine? Thank you. P.S. love this channel, just subscribed!
It can put you into limp mode but if it’s driving fine you should be ok for now, would definitely get the bypass kit soon as I could
@@crutchfieldautomotive7936 You recommend that as opposed to just replacing the whole system? I haven't done any research on a bypass kit. Is it a difficult job to perform? Thanks
Either will work, bypass is much more simple. What’s the primary use of the vehicle?
@@crutchfieldautomotive7936 Daily driver. I live in Atlanta, Georgia. Not sure about the legality of it. Would the truck pass emissions with the kit installed?
Being in Bama I haven’t run into that, let me do some digging, it should
The lights came on on a very cold morning a few days ago. I looked up a bunch of videos and read some threads, but no one seems to mention my specific issue. It makes me wonder if I have bigger problems or did it just go unmentioned.
In addition to the light show, the RPMs go very high before it shifts (if it even does). However, it almost shifts normally if I keep the RPMs under 2000. Still, even after gently building speed, the RPMs just shoot up yo 3-4000 if I hit the gas.
Does that sound familiar to anyone? I’m desperate.

What are your codes?
My GX lights came on, bought the gas cap from my local dealer, I drove it about 20 miles so far and lights still on, I also disconnected the negative on the battery to reset it, then the lights went away but came right back, any other suggestions or how long you have to drive it til lights go off? Thanks in advanced!!
Still need to pull codes to be sure it’s actually the emissions leak codes I mentioned first
@@crutchfieldautomotive7936 I will bring it asap, thanks again!!
P0138 and P2195 are the codes that I got, was advised that are related to oxygen sensors, can you advise, thanks again!!
2195 is bank 1 sensor 1 faulty showing lean
0138 is showing faulty rich
May change the sensor but try cleaning the mass air flow sensor and resetting lights first
@@crutchfieldautomotive7936 thanks for your quick response, have a great day!!
Wow.. that def worked!! Thank you!
Awesome! As long as it’s the evap codes it should work
Awesome
Thanks again !!!! 👍👍👍
I got those lights on my 2007 Toyota tundra.. it drives fine no weird noises it gots lots of power.. but I'm still worried I just bought the truck a week ago and got it shipped to me thru crowley hopefully when I try this tomorrow it solves my problem. Thank for the information
What’s the code pulling?
@@crutchfieldautomotive7936 I'm taking it to get chk tomorrow I'll let u kno
What if all of the lights except check engine light? Thanks!
Have you had your codes read recently from having a check engine light on?
Could be the ABS in this case and it would just need reset with a good code reader that a mechanic would keep on hand. If it was read with a cheap one it takes the calibration away. Let me know if you haven’t had it read recently tho
Thanks guy
Thanks you so much for this video. Worked
Awesome let it work. Sometimes it will
I got a p0430. Does this mean I have to replace the cat?
There’s a chance you’ll have to, has it been reset and come back on? Any other symptoms?
@@crutchfieldautomotive7936 I reset it and after driving 30 miles it comes back. I replaced the fuel cap and o2 sensors no avail. :( no other code just the p0430 but car runs fine.
@@pacificobernardo463 gonna need a local shop to look at it, but sounds likely to be the cat itself if you’ve done all of that 😔
@@crutchfieldautomotive7936 😞 thanks man
@@crutchfieldautomotive7936 by the way have you change the cat and where do you get the parts. I live in CA unfortunately.
Vsc trac check engine light on and now car will not drive! If i go to put it in park the gear grinds. Try and put it in drive and nothing
Gotta know the codes, the gas cap is only a good solution for evap codes. Common, but it’s not the end all. Pull the codes if possible and let us know what you have. Sounds like your transmission may have some issues
Sounds like ur transmission is gone
Good idea
Well after I wash the video I got out and check my fuel cap by retaining it and don't work but the very next day I stop at AutoZone and got one and immediately my lights tur off
Did he say “therefore we get a lot better fuel economy” 😂😂
Only if you have an evap leak, and even then it would be negligible 🤓
@@crutchfieldautomotive7936 I have a 2012 GX460 Premium. The “4LO” light is orange and blinking; check engine is illuminated and the display by the speedometer says “TRAC OFF.”
My gas cap DOES NOT make clicks anymore so I’m headed to O’Reilly to get a new one. Hope it works!!! I’ll report back.
What is the worst outcome of have the vsc light come on?
With a check engine light? Can be as bad as a blown engine
@@crutchfieldautomotive7936 Lol oic...
?
The codes have to be run, the evap code is just the most common one I see
Well, $1200 later, this turned into a fuel neck replacement:-(
$1200 for the fuel neck 😵
@@crutchfieldautomotive7936 Had to drop the fuel tank?
Code popped again AFTER the work.
Still sounds high for dropping a tank twice in my opinion
this happened to me, but i was parked eating chipotle listening to music with my car half on for like half a hour, my car got those warning lights but it seemed like the car was struggling to turn on and made some weird bubbling noises. Roadside assistance booted the battery and the car turned back on with those lights still on but this morning theyre all gone. Any chance anyone could help?
I had the exact thing you've experienced, alternator was found faulty, replaced it and now the lights came back but with no driveability issues though
for me the battery had a connection problem, just used a screwdriver.
