Vehicle make/model = 1999 Pontiac/Grand Am
Mileage = 98000
Engine size = 2.4L
dash lights = ABS light comes on intermittently when driving car
codes = none
work done prior = Replaced front brake pads and rotors
work done to repair = none
tech = JK
question = Just wondering what would be the likely cause to make the
ABS light come on right after replacing the front pads and rotors. Is
the sensor on the caliper very sensitive and easily damaged when
replacing pads?
Any information would be helpful. Have replaced many brakes and never
ran into this problem.
JK:
Hello and welcome.
The sensors are part of the hub, and are not that sensitive, unless you had to really hammer on
the rotors to get them off. Speed sensors fail as any other component can fail. You may also
want to check the harness from the back of the sensor to the the body. Pull off plastic cover,
they have been known to have the wires break inside the insulation. Just give a tug on each of
the two wires at the connector and up the harness and look to see if the wire is stretching.
To be sure it is a front sensor problem, you will need to have the system scanned for ABS codes
