ABS sensors are essential components of an anti-lock braking system. If they become defective, this could activate an ABS code and trigger its light to illuminate. Replacing an ABS speed sensor is fairly straightforward if you have access to a multimeter and standard tools – even at home!
Cost to Diagnose
ABS sensors are car components that monitor each wheel rotation’s speed, relaying this data back to your vehicle’s computer. As part of its anti-lock braking system, this sensor helps maintain grip during hard braking or on slippery roads. When this sensor breaks down, your brakes may feel unusual or erratic and its warning lights illuminated, thus necessitating immediate attention in order to avoid further damage to your vehicle.
The sensor is installed near the road surface on each wheel hub, making it exposed to dust, debris, precipitation, salt and other potential road hazards that can wear down its electrical connections and stop working properly. As well as ABS use, roll stability traction control and hill start assist rely on this sensor as well.
Your mechanic will conduct an ABS diagnostic test to assess if one or more sensors is defective, as well as checking all other wheels’ sensors to make sure they’re functioning optimally. With this information in hand, they’ll replace and reset the ABS light on your dashboard accordingly.
A skilled mechanic should be able to quickly and efficiently diagnose and repair an ABS sensor. They’ll begin by conducting an ABS diagnostic test and inspecting its wiring; once complete, they’ll remove the sensor from its wheel knuckle location if necessary; replace with new wiring; reconnect new wire; then install sensor again before clearing all codes for ABS codes subsequently lowering car.
ABS sensor failure often results from physical damage, caused by accidents such as collisions or striking obstacles such as potholes. Corrosion also poses a threat, particularly if water enters through its connector, while electrical issues or open circuits could further compromise its integrity.
ABS sensor failure symptoms typically include illuminated brake, traction control and stability control warning lights on your dashboard. Ignoring these warnings could result in further vehicle damage as well as creating safety risks to both yourself and other drivers. As soon as the warning lights appear on your dashboard, have it checked out ASAP because early intervention will significantly lower repair costs compared to late diagnosis and repairs.
Cost to Replace
ABS sensors (or wheel speed sensors, as they’re sometimes known) are crucial components of anti-lock braking systems, providing information to the ABS control module when activating brakes. When these sensors malfunction, however, their function becomes compromised and can create problems with other systems like traction control system, roll stability control or hill start assist which rely on them – drivers should be mindful of this risk and replace any malfunctioning sensors immediately.
When sensors fail, they send a diagnostic trouble code (DTC) to the ABS module and activates its warning light on your dashboard. If after inspecting all sensors and wiring connections thoroughly, your ABS warning light still illuminates, it would be prudent to refer back to your service manual for additional details on its cause.
Most auto parts stores sell replacement ABS sensors at relatively reasonable prices; however, installation can be more complex than simply plugging it in. An experienced mechanic should perform this work to avoid needlessly costly repairs in the future; you can hire one through Fiix as well to perform this work at your home or office location.
First, disconnect and raise your vehicle on jack stands before disconnecting its negative battery cable and removing a wheel using a lug nut socket set to loosen bolts holding in your sensor. After these bolts have been taken out, disconnect its electrical connector from its mounting and remove it altogether if possible; depending on whether or not your sensor is located within a hub assembly itself this step may also need to be completed before you can take this step.
Once installed, test the sensor to see if it works as expected before proceeding with replacement and diagnosis of the problem. Although not difficult to do correctly, performing this task does require experience working on cars for it to work effectively.
Getting an ABS sensor replaced quickly may help prevent unnecessary repair costs in the future, and checking reviews online of any auto shops before making your decision can be helpful in finding quality service at an affordable cost. In addition to the replacement cost itself, other costs related to repairs will likely apply as well; though, often these expenses are far lower than expected.
Cost to Repair
Replacement ABS sensors will vary based on your car’s make and model as well as how many sensors are installed behind each wheel rotor – some vehicles use four, while others only two sensors per wheel rotor. They’re integral parts of an anti-lock braking system (ABS) or traction control system (TCS).
If you’re experiencing difficulties with these systems, it may be time to replace your ABS sensor. A defective ABS sensor could cause your wheels to lock up unexpectedly and place you and your passengers at risk, while it also compromises stability control and traction control systems so they no longer function as intended.
An effective way of diagnosing problems with an ABS sensor is using a scan tool capable of reading ABS codes. Once you identify which sensor is causing issues, simply remove and install a new one as soon as possible.
Dependent upon the make and model of car you drive, professional assistance might be required to install or replace an ABS sensor. With some basic tools and mechanical know-how at hand, however, this process should take less than an hour and half.
First, inspect the ABS sensors for damage or corrosion by disconnecting the main harness and using a multimeter to check connections. You can also purchase special contact cleaners designed specifically to maintain clean contacts within these wires – keep in mind that millivolt signals travel down these wires, so any resistance can become an obstacle to proper functioning.
An indicator that a sensor has failed is when your speedometer stops working – this poses a significant safety risk as you’ll no longer know how fast you are driving. Since your speedometer is connected to your ABS sensor, any malfunction will also adversely impact it and the subsequent speedometer readings.
Use a multimeter to assess your ABS sensor by measuring voltage between its two terminals. If your ABS sensor is malfunctioning, a negative voltage reading on both terminals will indicate this; otherwise, positive voltage should indicate proper functioning.
If any of the symptoms listed above appear, it’s time to visit a professional mechanic. A qualified auto repair shop will be able to identify whether an ABS sensor is responsible and install a replacement at an affordable price; replacing one will keep your safety features intact for less.
