I have a 92 LSC S/E and the check ABS light is on.After checking the codes I found that the right rear sensor is bad.I found a new sensor and tried to replace the old one but I can't figure out how to remove the old one from the car.I took off the caliper,rotor and dust shield.Took the one screw out that holds the sensor on but I can't get it to come off.Any ideas on maybe what I am doing wrong?

someone told me one of the rear brakes has something to do with the parking brake.

From the 1989 shop manual 12-32-18
...
6. Remove the wheel sensor E8 Torx®head retaining bolt. Slip the gromet out of the rear brake splash shield and pull the sensor wire outward through the hole.

You're welcome but don't thank me until it's fixed :)

Do plan on doing anything else while you have the wheel off?

My ABS system is not functioning and it won't even let me pull codes. Any ideas?

Yup.
Check for power.

Is the ABS & Brake lights coming on?

I have to apologize, I have not had the time to really troubleshoot this properly. I was just throwing it out for a first reaction.

No I have not checked the power to it, but I am also unsure as to where to check the power to the abs computer. Neither my ABS or my brake lights are one, but I have not checked to see it the bulbs are good.

Oh, and I got your email Oldschool. Thanks.

You're welcome.
