The rear wheel sensors are the most likely to go. They are intergrated into the wheel bearing assembly and there is no repair when they go. You have to replace the entire bearing unit. Raise the vehicle and remove the tire to check the electrical connector behind the wheel. It has two contacts. If the circut is open or it does not change state when you spin the wheel, the sensor is bad. You can order the bearing on line of get it from a well stocked parts supply. Price ranges from $85 to over $160.
A reputable garage will charge anywhere from $500 to $750 to do the job depending on where you live.
If you are a serious DIY mechanic, don't let this job scare you off.
My best advice is to test the new part BEFORE you disassemble the wheel, brake and hub. You can plug in the new part and see if the ABS and Trac lights go off. If they do, you have the right side.
Search the web and you will find some great diagrams and sequence info on how to proceed.
I did mine for less than $100 in parts and 4 hours on a rainy day.

Re: my low trac ligth, and abs is on
You vehicle had (4) sensors one on each wheel my advise it to get your car on a code scanner (ex. snap -on, OTC etc) and that will tell what exactly is the problem, you can't guess. You will be wasting your time. Take it to Auto-Zone they do a check for free. Good Luck

This soundslike a bad speed sensor, you will need to have the computer scanned for codes, the computer turns on the light and stores the code, the code will tell you what has gone wrong and with some testing you can find the problem, the most common problem could be a bad wheel speed sensor, both light are on due to the abs problem because the trac control uses the abs speed sensors to watch wheel speed so if the computer sees a problem with the abs it turns off the trac and turns on the light. after the abs is repaired the trac light will go out, start by having the codes read, a scan tool is needed to get the codes, there are many auto part stores that scan the computer for free but i dont know if they scan for abs codes, you will have to check that out. good day.
TAKE CAR TO A GARAGE OR DEALERSHIP HAVE THE ABS BRAKES AND TRACTION CONTROL CODE SCAN.YOUR ABS BRAKE SYSTEM WILL COME ON ADJUSTING BRAKE PRESSURE TO AVOID A SKID.THAT WHY LOW TRAC LIGHT COMES ON. MOST OF THE TIME WHEN YOU SEE LOW TRAC LIGHT DRIVING ON DRY ROADS PROBLEM IS IN THE ABS BRAKE UNIT OR BAD WHEEL SPEED SENSOR.
MOST OF THE TIME WHEN ABS LIGHT AND TRAC LIGHT TURNS ON.YOU COULD HAVE A BAD WHEEL SPEED SENSOR.BEST TO TAKE CAR TO DEALERSHIP LET THEM DO CODE SCAN ON ABS BRAKE SYSTEM TO SEE WHAT CAUSING THE ABS AND TRAC LIGHT TO TURN ON.
brake fluid light goes on when the fluid is low. The traction control light may go on as well if the module detects a fault in the traction control system. The abs light may go on at the same time as the trac light if the wheel speed sensor is not sending a believable signal to the abs/trac module.
If one of the wheel speed sensors is faulty, or a hub is bad, that can cause the problem described.
The ABS and traction off lights usually indicate a bad wheel speed sensor. I can't remember if the service light came on the three times mine went. The most common one to fail is the left front.
Try this cheap fix first.
Remove the left front wheel speed sensor, clean and reinstall it. They are magnetic and some times road debris will block the sensor. If that was the problem the ABS and traction lights will go off when you start the car.
Your second option is to have the shop scan the vehicle trouble codes, usually this costs an hours labor.
Yes, The light should clear after fix the problem. Check the connection on the sensors. Theres 4, one at each wheel. If you have air in the lines the ABS light will come on. To bleed go left rear, right front, right rear, left front. Don't let the reservoir go dry. Brake fluid should be changed every 30,000 miles
You can test the wheel speed sensors by unhooking the connectors and put ohmeter test leads on the sensor terminals should read around 1100-1600 ohms also the connectors themselves were bad for wires breaking inside the insulation at the connectors from flexing when the wheel is turned back and forth..Note excessive wheel bearing noise from bad bearings have also been known for interferring with clean abs signal also causing abs codes good luck
The steering wheel position, wheel speed sensors, and ABS systems are all used to provide traction control. You likely have a failure of one or more systems. Scan the ABS system and it will provide codes to help the diagnosis. Wheel speed sensors fail often, and it is likely one or more of these is contributing to the problem.
low trac light and abs light run hand in hand. first thing id check is the code stored in abs module. youll almost guaranteed to find a bad abs wheel sensor--which to replace is a wheel hub assembly ....hope that helped you out
