your abs sensor light is on probably becuase the abs in one or all of your breaks are not working, take it to a mechanic so they can tell you if that is for sure the problem.
Check your ABS sensor
Possible abs sensor failure.
You may have damaged an ABS sensor or ABS sensor wiring. Go back and check each wheel.
Bring to a shop that has an ABS scanner to determine problem
replace abs sensor on back axel.
Likely a dirty abs sensor on one of the wheels
The ABS light will illuminate and the ABS function will not work if needed.
in my fiat punto (51 plate) i had the abs light on constantly. This could simply be down to having a dirt covered ABS sensor or the ABS sensor just being damaged. I paid about £30 for an aftermarket ABS sensor. its a simple fix and shouldn't be too costly.
You could, but the ABS light will stay on.
It means that there is a problem with the ABS system and you need to get it serviced.
You don't have to. When you have fixed the problem the abs light will reset itself.
