Toyota/Lexus “VSC Off” & “Check Engine” Lights On

Toyota/Lexus “VSC Off” & “Check Engine” Lights On

Posted on November 29, 2020 by Mitch Bartlett Leave a Comment

A common problem with Toyota and Lexus vehicles is the owner may find the “VSC OFF” and “Check Engine” lights illuminated simultaneously. What is the meaning of this?

VSC stands for “Vehicle Stability Control“. It is likely that “Traction Control” will not work while this light is illuminated. On some vehicles, the “skidding vehicle” or “TRAC OFF” light may also be lit as well.

Most Toyota owners will find that when the Check Engine and VSC lights are lit, there is a problem with an O2 Sensor or gas cap. Try tightening or replacing the gas cap for a hopefully cheap fix.

To be sure of the problem you may want to take your vehicle to an Auto Zone or NAPA store to have them plug in a code reader to determine the problem. Another option would be to take the vehicle in for service.

If your problem turns out to be O2 sensor related, you can continue driving the vehicle without problems, but you may not achieve the most efficient gas mileage.

O2 sensors can be difficult or easy to replace yourself depending on the make and model of the vehicle. Some require access under the vehicle, while others are accessible under the hood.
