My ABS light just came on. I have the TopDon scan tool and the code that came up is C0040 Right front wheel speed sensor, how involved is it to change the sensor?
thank you

It not too bad, you will need to raise the car up and jack stands (front) and remove the front wheels, these guides can help and I have included how to change the wheel speed sensor out in the images below.
