Abs senor is going bad

ABS thinks you are skidding, and is applying the brakes on and off. Likely one of the ABS sensors is bad.

have tires checked and rebalanced --if rotors were cut have rechecked if new than need to check the cv axles one of the axles possible going bad-- also steering components worn or loose --also bad shock or ball joints

Problems with ABS can be frustrating. You have senors on the front wheels, you have wires that run to the sensors, plus you have the ECU mounted to the master cylinder or on the fire wall depends on other options. Now the wheel sensors work like little alternators. Your wheels will have a gear that the senor reads as the wheel turns and then creates an A/C voltage that tells the ECU unit that the wheels are turning. Having a ABS code could mean that wiring to one of the sensors is broken or has fallen off, or is corroded at the plug end. Your ABS system has four major parts the ECU, an ABS hydraulic unit and the wiring harness to the wheel sensors, then last the sensors themselves. You will need to check all the wiring harnesses to each If you have a multi meter you can read the voltage of each wheel sensor at the other end of its wiring harness. Jack up the front end and find the end of each wheel sensor harness and spin the wheels by hand. you should get a reading on the AC voltage scale of about ..45 volts. not quite a half volt. when the wheel stops the meter should go to zero. spin the wheel and the meter should show voltage. That will tell you if the sensor and the wiring is good. The ECU has no trouble shooting it is good or bad.can't help you there. same with the Hydraulic unit. Most times it will be a wire broken or a bad wheel sensor. Good hunting.

if your abs light is on a code can be retrieved naming the possible culprit a wheel speed sensor or the abs module could be faulty if you have no light on then i would definately say the module is bad

if it were the rotors it only happens when braking take in have them turn rotors see what happens good luck

There's speed sensors at each wheel. You may have got some contamination in front of one of them... sounds like the abs is trying to compensate for un equal speed at each wheel... and something may be blocking a proper read at one of the wheels...

sounds like u need front brake pads and rotors i would check brakes first if ok then i would check front wheel bearings but cv joints make a clicking sound usauly when turning

Is it possible that you are hearing the abs pump running in the engine compartment? It sounds like an ABS problem with one of your wheel speed sensors.

ok im going to go threw the list of overall problems with electrical
alternator wareing out you might not know but your alternator was used from before overhaul this could have been a problem before other problems replace this

now seperate problems down the list
power windows- you had overhaul done and i hope the mechanic marked the electrical lines the relay junction box if not then he got a relay wire crossed with another wire

steering bars for vehicle can be worn have checked by mechanic

abs lights- faulty sensors bad or worn hardware warped rotar bad bearings
always do either front together or back together brake install or all at same time with brake installs never do a side of brakes this throws the whole vehicle off its running smooth and stopping smooth

a/c this comes back to the relays in relay compartment this could have been switched with door relays you need to have the wireing checked for this

the brakes alone are by self there own problem so yes these are seperate problems

you will want to get a computer diagnostics and a free brake inspection at any brake master i found that they do more than just brakes and its really helpful in diagnosing problems for free then telling you what you need keep in mind brake masters
i hope this helped seeing that im not actually there in person to see vehicle
