Buick ABS Sensors Cleaning

The Mercury Mountaineer features a anti-lock brake system for the rear wheels only. This system uses a sensor to measure the rotational speed of each wheel. The system adjusts the amount of braking power each wheel receives when the brake pedal is depressed. This prevents the wheels from locking and helps to provide stable deceleration. The anti-lock brake sensor on your Mountaineer can fail, requiring replacement. Replacing a rear anti-lock brake sensor is a repair job that most do-it-yourself mechanics can complete in under an hour.


Things You'll Need:
Adjustable wrench
Socket wrench


Disconnect the negative battery cable with an adjustable wrench.


Clean the axle housing around the sensor with a rag or shop towel. Disconnect the electrical harness from the sensor, located on the axle housing.


Remove the bolt from the sensor with a socket wrench and remove the sensor from the axle.


Lubricate the new sensor with a small amount of engine oil. Install the new sensor using the mounting bolt and tighten it with a socket wrench.


Connect the electrical connector to the sensor.


Connect the negative battery cable with an adjustable wrench.

ABS Speed Sensor Symptoms

The anti-lock brake (ABS) system uses sensors that send data to the ABS module which will activate it during wheel lock. These sensor mechanisms are installed at the wheel, and is usually made up of two components. There will be a reluctor wheel or tone ring seated on the axle which will spin with the wheel, and either a magnetic or hall effect sensor which works together to send data to the ABS control module. Over time, the reluctor wheel may become dirty or damaged to the point where it can no longer provide a consistent reading, or the magnetic/hall effect sensor may fail. When either of these components fail, the ABS system will not function properly and will require service.

Different cars will have different ABS sensor configurations. Older vehicles may have only one or two sensors on the entire vehicle, while most new ones will have one at each wheel. Individual sensors at each wheel allow for more precise readings and operation, however, it does leave the system prone to more problems. When an ABS sensor fails, there are usually a few warning signs that will warn you that there is a problem.
The ABS Light comes on

The most obvious sign of a problem with the ABS system is that the ABS Light will come on. The ABS Light is the equivalent of the Check Engine Light, except only for the ABS system. When the light is illuminated, this is usually the first sign that will be displayed indicating that there may be a problem with the ABS system, and perhaps an issue with one of the system’s sensors.
Decreased stopping time

During heavy braking conditions the ABS system should automatically activate to aid in slowing down the vehicle, and traction loss and skidding should be minimal. While we should try to practice regular driving habits that avoid heavy braking situations, if you do notice that the vehicle is taking longer to stop under heavy braking situations, or is experiencing traction loss and skidding, then that may be an indicator of there being a problem with the system. The ABS system is typically made up of only a few components - the module and the sensors - so a problem in its operation will either be with the module or the sensors.
Less stability under icy or wet driving conditions

Over time, most drivers will become familiar with how their vehicle handles under certain conditions, including slippery conditions, such as driving on wet or icy roads. A properly functioning ABS system will minimize any sort of traction loss, especially under wet and icy conditions. If when driving under wet or icy roads you experience any sort of tire slipping or loss of traction for more than a brief moment when stopping or taking off, then the ABS system may not be functioning correctly. This is typically due to either a problem with the module, or more likely, a problem with the sensors.

If your ABS Light comes on, or you suspect you may be having a problem with one or more of the ABS sensors, have the vehicle inspected by a professional technician, such as one from YourMechanic, to determine the exact nature of the problem, and if any repairs need to be made. They will also be able to replace your ABS Sensors if needed.

The anti-lock braking system is an electrical system that prevents your brakes from locking up during braking. Anti-lock braking systems (ABS) prevent fishtailing and other unexpected dangers when driving in bad weather conditions. When the ABS sensor comes on in the car, you may have an issue with the ABS system. Knowing how to troubleshoot the ABS sensor problem may prevent a nasty accident from a faulty ABS system. You may even find that the ABS sensor is firing without a proper issue behind it.


Things You'll Need

• Fuse
• Voltmeter

Inspect the brake fluid level of the car by lifting out the brake fluid dipstick and checking the level on the stick. Fill the brake fluid if necessary.


Listen for grinding noises from the brakes. This indicates a problem with the brake cylinders or pads, and not an issue with the ABS. Increased pressure needed on the brake pedal for regular braking also indicates an issue.


Turn the ignition key "On" and "Off" to turn on the car's electrical system to see if the ABS light resets. If not, further troubleshooting is needed.


Check the fuse for your ABS unit. The fuse is inside the fuse panel inside the car. Check the resistance level of the fuse and the fuse panel using a voltmeter. Set the voltmeter to the resistance setting indicated in your car manual, and check the fuse port by inserting the probes from the voltmeter into the port. Check the resistance value against the value in your manual.


Unplug the main harness for the ABS system controller, and plug it back in to reset the system. If the warning light still comes on, take your car to a professional mechanic.


Have the mechanic run an ABS controller diagnostic. This costs less than $100, and tells you where to look by giving you an error code that indicates the source of the problem
