What Does it Mean When Check the Engine Light On and TRAC Off?

Check engine light on, TRAC off is an indication that the traction control has been disabled because of a problem. The light could be caused by a number of things, including a bad wheel speed sensor.

It is possible that the controller, the vehicle speed sensor, or the wheel speed sensors are all failing.

The best place to start would be to have your mechanic use a scanner and see what codes come up when you are driving around. Then can then follow up with any repairs needed.

Why did my traction control and check engine light come on Toyota?

If the traction control light and check engine light come on your Toyota, it means that one or more of your vehicle’s systems are not working properly.

There are a number of reasons why these lights may come on, but they usually fall into one of three categories:

  •  Bad Wheel Speed Sensors – This is the most common reason for these lights to come on. If one or more of your wheel speed sensors are not functioning properly, it can cause problems with other systems in your vehicle.
  •  Bad Steering Angle Sensor – This sensor measures how far your wheels turn from left to right and sends this information to the main computer so that it can calculate where your vehicle should go based on how much you turn the wheel. If this sensor stops working correctly, it can cause issues with traction control as well as other aspects of driving performance.
  • Bad Road Conditions – Although this is not technically a problem with your car itself, bad road conditions can be one of the main reasons why these lights will illuminate your dashboard. If you drive over bumps or potholes while they are covered in snow or ice, they could damage some of the wirings underneath your car’s bodywork which would result in these lights coming on.
  •  Bad Ignition Coil – The ignition coil works with the spark plugs to create an electric current that ignites the fuel in your engine. If it fails, the engine will not start. The coil should be replaced if it fails.
  •  Loose or Broken Gas Cap – A loose gas cap can cause fuel vapor buildup in the tank and lead to misfires, poor performance, and even complete engine failure if not addressed promptly. A broken gas cap might allow fuel vapors to leak out of the tank directly into the engine compartment and cause combustion problems.

Can you drive with TRAC off light on?

Your vehicle may be able to drive without traction control, but it is not recommended that you do so.

How do you fix a TRAC off check engine light on a Toyota?
