Are " wheel speed sensors" the same thing as an ABS sensor?
I was driving today, normal driving conditions, i went up the road to grab breakfast came back no lights.

I left to go to gas station and my ABS light came on same time my TC lights came on.
Got under the front two wheels in gas station parking lot and replugged in each ABS / wheel speed conector.
i drove home no light on dash.
I leave for a odd job and second i put it in reverse to leave my place the light both pop back on.

Dealership wants $120 to look at it. then another $650 bucks to replace an ABS sensor cause it is built in the Hub.

The hub with sensor is at Auto Zone for $105.00

Are " wheel speed sensors" the same thing as an ABS sensor?
I have no idea can i clean this sensor?
What can i do ?
Has anyone had these issues?

(i understand not alot cobalts even have ABS or Traction Control)
If i could i like to remove the whole system, or fix it.
I hate seeing CEL or trouble lights on my dash.

Any ideas:

my dads says all chevrolets have sensor issues.

abs and wheel speed sensors are not the same thing. abs uses the wheel speed sensors.

and what the hell is going on in your sig?

I've had this with the ABS light. I can just be sitting with my foot on the brake, e-brake on, and it'll come on. I just kinda ignore it though. Stealership has no idea what could be causing it either.

are you lowered? or recently lowered?

i had this issue about a month after lowering my car. its because of the rear wheel wires connecting to the hub. when u lower the car they tend to cut or break. go check both back rear wheel hubs, and re-wire anything that looks suspicious.

my cav had abs problems (but it was a junker to me, so I ignored it), but I've not had an issue with my cobalt yet
