LS430 check VSC light on after check engine light on

Engine pipe leak turned on the 'check engine' alert. Did not have time to fix until recently. Before check engine fix, I took the car to check. After the checking, another new issue pop up: 'check VSC'. Now the check engine issue is fixed, but the check vsc issue stays. Help

My car (06 GS430) began giving me more frequent "Check VSC" warnings. (Code P0455 in my case. Really glad I bought that OBDII tool--resetting the codes is a snap!)

I knew that a loose gas cap could cause this, so normally I just give it a twist and it tightens. Now I found that no matter how many "clicks" I tightened the gas cap, it would not cinch down snug. The lightest turn the opposite way would open it.

I was all set to head over to CarQuest for a replacement filler cap. But I thought I'd inspect mine first just to see why it stopped holding. Upon inspection, I saw that what holds the cap in place is compression of the rubber O-ring at the back of the cap, which compresses against the filler neck. That apparently was no longer happening.

I carefully removed the O-ring from the cap--using screwdrivers to lift it over the edge of the groove it sits in. Like removing a bike tire from the rim--work your way around. Then I cut a strip of electrical tape about 10" long, and 1/4" wide. I wound this into the curved groove where the O-ring normally sits, just to build up a little thickness. Put the O-ring back in place. Done.

Now the cap tightens like it's supposed to, and thus far, it has stopped the VSC error codes. Don't know if it will fix your issue or not, Good luck.

Vcs/vcsoff /lightsdo not go off


VSC is a system that helps prevent side skids and help stabilize the vehicle while turning on a curve. Is the Check Engine Light on also? (picture of an engine). If the check engine light is on then have someone fix that first because if there is a fault in the engine controls then your vehicle will turn off the VSC system automatically. If no Check Engine Light then either a re-calibration by a repair shop, a bad part in the VSC or the switch is turned off.

Vsc code c1336


That code relates to a crankshaft position sensor signal. It you have a check engine light come it disables the VSC and Trac system. Until you get that sensor fixed the VSC and the TRAC system will be inop. So whenever you have a check engine light come on that is what you will see. Even though you cancel the check engine light the fault still exists and the VSC/ TRAC light will come back on. That is a sure way to tell that something is wrong.

Low Fuel Pressure


when check engine light comes on VSC is disabled. small leak is for evaporative system (to prevent fuel vapors from entering the atmosphere) small leak is A leak less than forty thousandths of an inch, it could possibly be a gas cap not fully tightened,leak in a vapor line,leaking fuel filler neck,gas tank leak,purge valve,vent valve just to name afew. clearing code will turn off both lights but if theres a leak lights will come back on.

VSC off VSC trac on as well as check engine light on but the car is working fine I've driven with both the lights on? Is there something wrong, what should I do? Should I stop driving and how can


VSC is vehicle stability/skid control. Find the button that turns it off and on. Push the button to turn it on and the light should go off. Most cases systems like these will have a light stay on any time they are turned off. If the vehicle is a 96' or newer call around to your local auto parts stores and you should find one that will scan your vehicle for free and tell you why the check engine light is on. If the two problems are related the scan should tell you what part of the VSC is malfunctioning.

How to fix GX470 lexus suv 2007 vsc/tract/ engine light on


On this make the warning lights all come on together, the check engine light is the cause of all.
Hello
When the service engine soon light (Also called the check engine light or engine management light) is turned on this is to alert you to the fact that Powertrain Control Module (computer) has detected a failure somewhere in the systems it controls you may not feel any difference in the way the engine runs, this can be the transmission or the engine or emission system, there are fault codes set in the modules memory for these faults. What needs to happen now is to have the powertrain control module scanned with a special tool called an OBD2 electronic engine control scanner or a OBD2 code reader. Once the code(s) are read then you must perform the diagnostics for each code and make the appropriate repairs based on the findings of the diagnosis that was performed, this is called doing "Pinpoint" testing.

Both the engine lights and the VSC warning light appeared on the dash simultaneoulsy this evening while driving - what might this be?


Had this happen to my '05 Vibe (Matrix evil clone) recently. Mechanic read & reset codes. The non-flashing Engine light showed 2 large emission leaks. The VSC could be any number of things. He said hopefully it was a false positive on the VSC... potentially expensive to fix. Lights stayed off for a couple weeks & are now back on. I'm planning on seeing him later today. Also, said stability light stayed off, it is still working. fwiw...

What is a vsc warning light on a toyota estima hybrid ?


It stands for Vehicle Stability Control When the VSC system takes control it activiates stability correction. The slip indication light flashes while the buzzer activates. The VSC is able to operate at all times except when the centre differential is locked. When the centre differential locks, the VSC-OFF light in the combination meter illuminates to inform the driver that the VSC function has been turned OFF. The centre differential lock is designed for freeing the vehicle if it is stuck in mud for example, however it would be difficult for the vehicle to free itself if the engine output were reduced due to the operation of VSC. Therefore when the centre differential is locked, the VSC function is turned OFF.If a malfunction occurs in the VSC system, the VSC warning light illuminates to alert the driver. If the vehicle with VSC begins to oversteer or understeer because of an emergency avoidance measure, or by excessive speed in a corner, VSC will automatically activate. By adjusting the engine’s power output and braking each wheel independently, VSC helps to return the vehicle to a ‘zone of stable operation’..
