My 2005 Mazda Tribute has an ABS warning light that comes on as soon as I reach 40 mph. It will remain on after that no matter what speed I drive until I turn the car off. The braking system appears to function normally with normal breaking even if the light is on. With hard braking the ABS performs as it should too, rapidly oscillating the braking force. If I restart the car and keep the driving speed below 40 mph the ABS light never comes on. Otherwise, the car runs great. What is causing the ABS light to come on at 40 mph and how do I fix it?
Take it to the Dealer along with $1500 and say “please fix this”…Or ignore it, keep the $1500 in your pocket and drive on…
You probably have a problem with a speed sensor.
