VSC and TRAC OFF lights came on? - Scion xB Forum

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.

I have the same problem with my 04 Sequoia, I wish someone would answer this question.

2000 toyota highlander just had oil changed and VSC lightis on.
what to do

I have both lights on in my 2004 van also I have the engine light on. i took it to the dealer and they found the Yaw Rate Sensor (Vsc & TRAC) bad. The part is about$ 405 and is under the drivers seat. The other problems is the Catalyst System (engine light) about $1000 for parts.I have about 147,000 miles on my '04 and the problems started about 130,000.

could be alot differnet things u need to take it some where to have codes scaned on it more than likely it a bad speed sensor but cant tell for sure until codes are scaned

how to solve the problem of p0031

The check engine light ,trac control light and VSC light are on. Does this normally represent a serious problem on a 2004 toyota solara?

Have you scanned both the engine computer and the abs computer? Because it is an abs problem, likely a wheel speed sensor.

The Trac light comes on automatically, in conjuction with the Check Engine Light. You need your vehicle scanned for DTC codes.
