My ABS and AdvanceTrac warning lights came on at the exact same time. Could this be a sensor?

Hi Barbara. Thanks for contacting us today. Usually when both of these warning lights illuminate, it’s due to a wheel or speed sensor failure - as both contribute to the Advance Trac and ABS system. It’s also possible that the ABS module is faulty - as it also impacts the operation of both systems. If the lights are illuminated, then an OBD-II trouble code has been created and stored in the ECU. A professional mechanic can complete a warning light inspection at your location to determine what caused the codes, which should lead them to a repair that will resolve both issues.

The ABS and advanced track share the same module and sensors to work correctly. You may have a sensor issue but would need to have ABS system tested for codes to see what code is stored and get the code tested to find the cause of the problem.
