VSC TRAC, TRAC OFF and CHECk ENGINE lights

Hi everyone. I have a 2006 Toyota Sequoia with 20,000 miles on it. Last week the VSC TRAC, TRAC OFF and CHECk ENGINE lights started coming on and staying on. I have been reading many posts on the net that talk about malfunction of the VSC TRAC sensor etc... Note that I have found that one of the small vacum hoses was loose and I put it back in its place. The air filter was very dirty. I checked that the gas cap is fine. I took the car to local toyota dealer (I'M In Dubai now) they said they can not read the codes on Sequoia made in US as they don't import them here. Anyone has tips for me to fix and diagnose this problem without getting the codes?

You have to know what code is stored to fix the problem. Toyota's will generally display a Check Engine light, VSC and TRAC light all at the same time, even if it's a simple problem with an oxygen sensor (for example). You can disconnect the negative battery cable for a few minutes, even though you should a scan tool should be used, to clear out the code.

    WHEN MY 2006 VSC/ TRAC LIGHT WAS ON I CHECKED ALL FLUID LEVELS AND LOW AND BEHOLD THE BRAKE FLUID WAS A BIT LOW, NOT EMPTY JUST LOW. I REFILED AND BLED BOTH FRONT AND REAR TWO PERSON METHOD AND THAT FIXED THE VSC LIGHT.

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.

Check engine light is on together with the vsc and trac light on my Sequoia 2003,what that means?
Hello. Many times the check engine light and VSC and trac are all on due to one or more bad sensors as opposed to any serious trouble. Begin by having your car's computer scanned. AAMCO transmission shops now offer a free scan as do some auto parts stores. Begin with that. Joe
please rate my answer as very helpful thanks.

VSC Trac and VSC Off and Check Engine lights are on. The lights were reset last week and they have come back on. What is my problem most likely and what are the costs going to be?
The computer turns your traction control off when it sets the check engine light. Thats why VSC lights come on at the same time. Have the local parts store see what code you are getting to find the problem.

2004 Sequoia. VSC TRAC, TRAC OFF, and Check
It is not hard to change the sensor, it just screws into a threaded hole. The light will not go out immeditaly, after the sensor is replaced. It needs to go thru a drive cycle. Your best bet is to replace the sensor and get the code cleard by whoever scanned it for the 0031 code.
