Lexus SC430 :: Code P0051 Together With VSC And VSC Off Lights
Feb 1, 2016
P0051 together with VSC and VSC Off Lights
Over the weekend I had multiple P0051 and VSC and VSC Off Lights CELs
I have reset them using my OBDII scanner. It keeps on coming back.
This means the BANK 2 SENSOR 1 (just before the CAT) is reading low temps and therefore throwing a code. I get this.
Question is why do the VSC lights go "ON" too?
This started when I installed my ScanGage e this weekend. This is a change point.
Before I go purchase a Denso sensor, I would like to perform a series of tests:
1.Remove the ScanGage e. Test drive if any of the CELs (P0051 and VSC) come back.
2.If the same set comes back, clear the VSC lights code using our home made device.
If the VSC lights disappear and the P0051 comes back, I will replace the BANK 2 SENSOR 1 Oxygen sensor. Prior to replacing, I will check for wiring issues on this sensor.

I have recently run through a large pool of water on the road and this shortly after tuned on the engine warning light and the " ! " light. Everything seems to feel Ok but had the OBD code read and it shows P0051 and also showed VSC. What to look for?

My check engine light came on.. so I took it to express tires.. And they said that they need to replace my vacuum hoses cause it busted ... well when I saw the guy used the obd checker thing.. after checking the codes.. i saw that when u turned on the engine.. the vsc on and vcs off lights came on..
So I figured after he fixed the problem.. it will go off.. well after he got done.. fixing the problem.. I drove away.. after bout like 2min.. i had to turn around cause the vsc on and vsc off came on.. and I told the guy to check.. And he used his checker.. and there was no problem.. and the "check engine" light is not on anymore.. just the vsc on and vsc off!!
Could the checker.. messed it up??? the vsc off button.. only works when the key is turned on.. " not when the engine started but right before it.. when the power comes on" so the button is working correctly.. it just comes on.. when i start driving the car...
And no they did not check my tire pressure or do anything to the tires or the wheels.. it just turned on.. when he inserted the obd thing to check..
And yes I read the [URL] .....
Is it dangerous to be driving with the vsc and vsc off light on??

So, my '06 XL just popped up a P0051 code, which is the bank 2, sensor 1 (the upstream A/F sensor that you can easily view upon opening the hood in the front exhaust manifold. Easy enough of a replacement on that one, but what about bank 1, sensor 1 (the upstream A/F ratio sensor on the firewall side of the engine)? I changed my oil today and I can access three of the four oxy/A/F sensors, but the upstream rear looks like a bitch! Out of curiosity, I called a local Toyota dealer and they said it would be 300.00 total to replace the hidden sensor on the firewall side. Does this amount seem realistic? I know that there is a TSB for this sensor that states to replace the exhaust manifold/cat assembly. I def. can't afford no 1700.00 crap right now!!

I have a check engine light for the Evap. the code there is a hose that comes off and you get the code. I have looked high and low for this hose, where actually this hose is or put a picture up so I can find it.

So this morning I started the SC up early to warm up a bit before I took off for work. Its 19 degrees outside. when I got into my car to leave the check engine light was on. Everything seem alright and the light not flashing so I thought I would stop by AutoZone to have code read. I was told T stat code. And that makes sense to me cause the temp gauge didn't hardly move off cold on the way to work. I noticed this once before when the temp dropped pretty low but didn't think anything of it.

My dash lights are very dim during daylight and marginally bright at night. This is for a 2002 Lexus SC430.

Just read that a clogged EGR valve is common and reduced performance and increases emissions. Need to clean this valve? Where is it located?? Just noticed tonight that there is not a lot of suction from my vacuum lines and I wondered if this is related. Plus I have a p0430.

So yesterday I had Error 3 code display on my cd player and after messing around with the device i was able to get it to eject all the cds. Thinking all was well, i tried to load one cd and it won't even respond to me pushing on the button. There is no noise or error code coming from the unit. Whats going on here?

Well I think I am finally getting to the end of my lighting problems. I have them all working except for the lights on the turn signal lever, the windshield wiper lever, the cruse control and the steering wheel. So all the light on the steering column are out. I cannot find a bad fuse. Which fuse it might be, or some other items to check?

I have just noticed my emergency lights do not work. Where the fuse is located. I tried looking everywhere. Before I unplug each one and see which is bad I wanted to get some info...

I just got this used sc430 I always wanted one but never got the chance to though, the car I got is American spec and I Hove few problems with it.
1- fog lights are always on
2- my mileage gage does not work but the rim is working effectively
3- ABS light always on
4- brake lights always on
5- Air bag lights always on
6- side rear viewing mirrors control not working
7- windows auto option is not working, other wise I can use them normal.
Note I took the car to garage and once connected to the computer, the computer was not able to connect as per as the mechanic if it makes any sense.
I love my car unfortunately I don't know much.

2002 SC430, 150,950 miles.
Had new front brake pads, re-surfaced rotors, new windshield fluid level sensor installed, 4 x wheels balanced and rotated on 8/11 at Lexus Dealer. Picked it up 8/13, drove 30 miles and it sat 8/14-8/16. Drove to work on 8/17, and on the 18 mile freeway trip home yesterday, the Brake and ABS dash lights came on as I was making a gradual left turn with damp roads.
Thought nothing of it initially, thought my knee had hit the e-brake as mine is very touchy and as long as you pull the release, the light goes away. Not this time. The Brake and ABS lights were on for 4 minutes, then eventually the VSC and VSC OFF dash lights also came on. Steering became difficult, checked brake fluid (ok), checked power steering fluid (ok). No leaks underneath, all fluid levels were just checked on 8/11 and were fine/topped off.
Parked it, set up an appointment and just dropped it off this AM. I've read brake booster, speed sensor, alternator, skid control unit .
I am hoping it's just the alternator, which makes sense with the difficult steering and the lights going on one by one. If the alternator isn't outputting enough volts, those lights will trip. I've had all O2 sensors recently replaced, other standard preventative maintenance done (timing belt, thermo, etc). I'm just hoping it's something manageable and not something that makes me wonder if the repair is worth it (vs the value of the car)...
There are no CEL lights, just the above (no codes to my knowledge).

So my sc430 keeps giving me trouble and all the lights come on while i am driving and then it shuts off on me. I could be wrong but i think it has something to do with a iphone connection that i have. I originally thought it was the battery so i replaced that and it was running fine for a day with no issues. Then today shortly after i tried to use the iphone connector the same thing happened.

y '02 SC430, which had been in an accident, is throwing a low voltage code and showing the airbag light. What was the reason for the code (C1336)?

The car has an obvious misfire and the scanner says its Cyl # 8. I tried the "italian" tune-up and under heavy throttle the miss goes away. I swapped coils and the miss stays with Cyl # 8. I pulled the injector, and can't see anything wrong.

Lately I have been working a lot with my cold air intake. One of the vacuum lines keeps popping off. Today I got a check engine light and VSC and VSC off light. Is that due to the tough idle caused by the disconnected vacuum line. I erased the code and so far it has not returned.

I would like to install puddle lights underneath the car...to come on when the door is opened. I came across this thread that shows these lights. There is apparently a rubber grommet in the driver's floorboard which can be used to snake the wire into the cabin. Where exactly is this rubber grommet on a 06 model? I tried to find it today but was unsuccessful.

Its not super cold but in Tampa ever since I installed my headers and its 60 or below i've gotten the VSC and ABS lights on in the dash after driving a little bit. Typically this is a cold morning type thing.
I reset the lights and it went away for a few days (it also got 30 degrees warmer) once it got down to 55 the lights came back on. Parked the car went in to work and when I drove home the lights were off (without re-setting the lights).
I know the codes can mean different things. The car is driving the same as always too- I have PPE headers, Ingen Intake, and a muffler delete.
